+# Cerberus Security Module - Comprehensive Remediation Plan
+
+**Version:** 2.0
+**Date:** 2025-12-12
+**Status:** 🔴 PENDING - Issues #16, #17, #18, #19 incomplete
+
+---
+
+## Executive Summary
+
+This document provides a **comprehensive, actionable remediation plan** to complete the Cerberus security module. Four GitHub issues remain partially implemented:
+
+| Issue | Feature | Current State | Priority |
+|-------|---------|---------------|----------|
+| #16 | GeoIP Integration | Database downloaded, no Go code reads it | HIGH |
+| #17 | CrowdSec Bouncer | Placeholder comment in code | HIGH |
+| #18 | WAF (Coraza) Integration | Only checks `<script>` tag, no real Coraza config | HIGH |
+| #19 | Rate Limiting | Burst field unused, no bypass list/templates | MEDIUM |
+
+---
+
+## Implementation Phases
+
+### Phase 1: GeoIP Integration (Issue #16)
+
+**Goal:** Enable actual IP → Country lookup for geo-blocking ACLs.
+
+#### 1.1 Current State Analysis
+
+- **Dockerfile** downloads `GeoLite2-Country.mmdb` to `/app/data/geoip/`
+- **Environment variable** `CHARON_GEOIP_DB_PATH` is set
+- **No Go code** imports or reads the MaxMind database
+- **Caddy config** uses `caddy-geoip2` plugin with `{geoip2.country_code}` placeholder (works at proxy level)
+- **`TestIP` service method** only evaluates IP/CIDR rules, returns default for geo types
+
+#### 1.2 Required Changes
+
+##### 1.2.1 Add GeoIP Dependency
+
+**File:** `backend/go.mod`
+
+```bash
+cd backend && go get github.com/oschwald/geoip2-golang
+```
+
+##### 1.2.2 Create GeoIP Service
+
+**New File:** `backend/internal/services/geoip_service.go`
+
+```go
+// Package services provides business logic for the application.
+package services
+
+import (
+ "errors"
+ "net"
+ "sync"
+
+ "github.com/oschwald/geoip2-golang"
+)
+
+var (
+ ErrGeoIPDatabaseNotLoaded = errors.New("geoip database not loaded")
+ ErrInvalidIP              = errors.New("invalid IP address")
+ ErrCountryNotFound        = errors.New("country not found for IP")
+)
+
+// GeoIPService provides IP-to-country lookups using MaxMind GeoLite2.
+type GeoIPService struct {
+ mu     sync.RWMutex
+ db     *geoip2.Reader
+ dbPath string
+}
+
+// NewGeoIPService creates a new GeoIPService and loads the database.
+func NewGeoIPService(dbPath string) (*GeoIPService, error) {
+ svc := &GeoIPService{dbPath: dbPath}
+ if err := svc.Load(); err != nil {
+  return nil, err
+ }
+ return svc, nil
+}
+
+// Load opens or reloads the GeoIP database.
+func (s *GeoIPService) Load() error {
+ s.mu.Lock()
+ defer s.mu.Unlock()
+
+ if s.db != nil {
+  s.db.Close()
+ }
+
+ db, err := geoip2.Open(s.dbPath)
+ if err != nil {
+  return err
+ }
+ s.db = db
+ return nil
+}
+
+// Close releases the database resources.
+func (s *GeoIPService) Close() error {
+ s.mu.Lock()
+ defer s.mu.Unlock()
+ if s.db != nil {
+  return s.db.Close()
+ }
+ return nil
+}
+
+// LookupCountry returns the ISO 3166-1 alpha-2 country code for an IP.
+func (s *GeoIPService) LookupCountry(ipStr string) (string, error) {
+ s.mu.RLock()
+ defer s.mu.RUnlock()
+
+ if s.db == nil {
+  return "", ErrGeoIPDatabaseNotLoaded
+ }
+
+ ip := net.ParseIP(ipStr)
+ if ip == nil {
+  return "", ErrInvalidIP
+ }
+
+ record, err := s.db.Country(ip)
+ if err != nil {
+  return "", err
+ }
+
+ if record.Country.IsoCode == "" {
+  return "", ErrCountryNotFound
+ }
+
+ return record.Country.IsoCode, nil
+}
+
+// IsLoaded returns true if the database is loaded.
+func (s *GeoIPService) IsLoaded() bool {
+ s.mu.RLock()
+ defer s.mu.RUnlock()
+ return s.db != nil
+}
+```
+
+##### 1.2.3 Update AccessListService to Use GeoIP
+
+**File:** `backend/internal/services/access_list_service.go`
+
+**Add field to struct:**
+
+```go
+type AccessListService struct {
+ db       *gorm.DB
+ geoipSvc *GeoIPService  // NEW
+}
+```
+
+**Update constructor:**
+
+```go
+func NewAccessListService(db *gorm.DB) *AccessListService {
+ return &AccessListService{
+  db:       db,
+  geoipSvc: nil, // Will be set via SetGeoIPService
+ }
+}
+
+// SetGeoIPService attaches a GeoIP service for country lookups.
+func (s *AccessListService) SetGeoIPService(geoipSvc *GeoIPService) {
+ s.geoipSvc = geoipSvc
+}
+```
+
+**Update `TestIP` method to handle geo types:**
+
+```go
+// TestIP tests if an IP address would be allowed/blocked by the access list
+func (s *AccessListService) TestIP(aclID uint, ipAddress string) (allowed bool, reason string, err error) {
+ acl, err := s.GetByID(aclID)
+ if err != nil {
+  return false, "", err
+ }
+
+ if !acl.Enabled {
+  return true, "Access list is disabled - all traffic allowed", nil
+ }
+
+ ip := net.ParseIP(ipAddress)
+ if ip == nil {
+  return false, "", ErrInvalidIPAddress
+ }
+
+ // Handle geo-based ACLs
+ if strings.HasPrefix(acl.Type, "geo_") {
+  if s.geoipSvc == nil {
+   return true, "GeoIP service not available - allowing by default", nil
+  }
+
+  countryCode, err := s.geoipSvc.LookupCountry(ipAddress)
+  if err != nil {
+   // If lookup fails, allow with warning
+   return true, fmt.Sprintf("GeoIP lookup failed: %v - allowing by default", err), nil
+  }
+
+  // Parse country codes from ACL
+  allowedCodes := make(map[string]bool)
+  for _, code := range strings.Split(acl.CountryCodes, ",") {
+   allowedCodes[strings.TrimSpace(strings.ToUpper(code))] = true
+  }
+
+  isInList := allowedCodes[countryCode]
+
+  if acl.Type == "geo_whitelist" {
+   if isInList {
+    return true, fmt.Sprintf("Allowed by geo whitelist: IP from %s", countryCode), nil
+   }
+   return false, fmt.Sprintf("Blocked: IP from %s not in geo whitelist", countryCode), nil
+  }
+
+  // geo_blacklist
+  if isInList {
+   return false, fmt.Sprintf("Blocked by geo blacklist: IP from %s", countryCode), nil
+  }
+  return true, fmt.Sprintf("Allowed: IP from %s not in geo blacklist", countryCode), nil
+ }
+
+ // ... rest of existing IP/CIDR logic unchanged ...
+}
+```
+
+##### 1.2.4 Initialize GeoIP Service on Server Start
+
+**File:** `backend/internal/server/server.go` (or wherever services are initialized)
+
+```go
+import (
+ "os"
+ // ...
+)
+
+// In server initialization:
+geoipPath := os.Getenv("CHARON_GEOIP_DB_PATH")
+if geoipPath == "" {
+ geoipPath = "/app/data/geoip/GeoLite2-Country.mmdb"
+}
+
+var geoipSvc *services.GeoIPService
+if _, err := os.Stat(geoipPath); err == nil {
+ geoipSvc, err = services.NewGeoIPService(geoipPath)
+ if err != nil {
+  logger.Log().WithError(err).Warn("Failed to load GeoIP database, geo-blocking will be unavailable")
+ } else {
+  logger.Log().Info("GeoIP database loaded successfully")
+ }
+}
+
+// Pass to AccessListService
+accessListSvc := services.NewAccessListService(db)
+if geoipSvc != nil {
+ accessListSvc.SetGeoIPService(geoipSvc)
+}
+```
+
+##### 1.2.5 Add GeoIP Reload Endpoint (Optional Enhancement)
+
+**File:** `backend/internal/api/handlers/security_handler.go`
+
+```go
+// ReloadGeoIP reloads the GeoIP database from disk
+func (h *SecurityHandler) ReloadGeoIP(c *gin.Context) {
+ if h.geoipSvc == nil {
+  c.JSON(http.StatusServiceUnavailable, gin.H{"error": "GeoIP service not initialized"})
+  return
+ }
+ if err := h.geoipSvc.Load(); err != nil {
+  c.JSON(http.StatusInternalServerError, gin.H{"error": fmt.Sprintf("Failed to reload: %v", err)})
+  return
+ }
+ c.JSON(http.StatusOK, gin.H{"message": "GeoIP database reloaded"})
+}
+```
+
+**Add route:** `POST /api/v1/security/geoip/reload`
+
+#### 1.3 Test Requirements
+
+**New File:** `backend/internal/services/geoip_service_test.go`
+
+```go
+func TestGeoIPService_LookupCountry(t *testing.T) {
+ // Skip if no test database available
+ testDBPath := os.Getenv("TEST_GEOIP_DB_PATH")
+ if testDBPath == "" {
+  t.Skip("TEST_GEOIP_DB_PATH not set")
+ }
+
+ svc, err := NewGeoIPService(testDBPath)
+ require.NoError(t, err)
+ defer svc.Close()
+
+ tests := []struct {
+  name    string
+  ip      string
+  wantCC  string
+  wantErr bool
+ }{
+  {"Google DNS", "8.8.8.8", "US", false},
+  {"Cloudflare", "1.1.1.1", "AU", false}, // May vary
+  {"Invalid IP", "not-an-ip", "", true},
+  {"Private IP", "192.168.1.1", "", true}, // No country
+ }
+
+ for _, tt := range tests {
+  t.Run(tt.name, func(t *testing.T) {
+   cc, err := svc.LookupCountry(tt.ip)
+   if tt.wantErr {
+    assert.Error(t, err)
+   } else {
+    assert.NoError(t, err)
+    assert.Equal(t, tt.wantCC, cc)
+   }
+  })
+ }
+}
+```
+
+**Update:** `backend/internal/services/access_list_service_test.go` - add tests for geo ACL `TestIP`.
+
+#### 1.4 Frontend Changes
+
+**File:** `frontend/src/pages/AccessLists.tsx`
+
+Update the test IP result display to show country code when geo-blocking:
+
+```tsx
+// In handleTestIP success callback:
+if (result.reason.includes("IP from")) {
+  toast.success(`${result.allowed ? '✅' : '🚫'} ${result.reason}`)
+} else {
+  // existing logic
+}
+```
+
+#### 1.5 Documentation Update
+
+**File:** `docs/cerberus.md` - Add section on GeoIP configuration and database updates.
+
+---
+
+### Phase 2: Rate Limit Fix (Issue #19) - Quick Win
+
+**Goal:** Fix burst field usage, add bypass list and preset templates.
+
+#### 2.1 Current State Analysis
+
+- `RateLimitBurst` field exists in `SecurityConfig` model
+- `buildRateLimitHandler` in `caddy/config.go` **ignores** burst field
+- No bypass list for trusted IPs
+- No preset templates (login, API, standard)
+- Frontend has burst input but it's not used by backend
+
+#### 2.2 Required Changes
+
+##### 2.2.1 Fix Burst Field in Caddy Config
+
+**File:** `backend/internal/caddy/config.go`
+
+```go
+// buildRateLimitHandler returns a rate-limit handler using the caddy-ratelimit module.
+func buildRateLimitHandler(_ *models.ProxyHost, secCfg *models.SecurityConfig) (Handler, error) {
+ if secCfg == nil {
+  return nil, nil
+ }
+ if secCfg.RateLimitRequests <= 0 || secCfg.RateLimitWindowSec <= 0 {
+  return nil, nil
+ }
+
+ // Calculate burst: if not set, default to 20% of requests
+ burst := secCfg.RateLimitBurst
+ if burst <= 0 {
+  burst = secCfg.RateLimitRequests / 5
+  if burst < 1 {
+   burst = 1
+  }
+ }
+
+ // caddy-ratelimit format with burst support
+ h := Handler{"handler": "rate_limit"}
+ h["rate_limits"] = map[string]interface{}{
+  "static": map[string]interface{}{
+   "key":        "{http.request.remote.host}",
+   "window":     fmt.Sprintf("%ds", secCfg.RateLimitWindowSec),
+   "max_events": secCfg.RateLimitRequests,
+   // NOTE: caddy-ratelimit doesn't have a direct "burst" param,
+   // but we can use distributed rate limiting or adjust max_events
+  },
+ }
+ return h, nil
+}
+```
+
+> **Note:** The `caddy-ratelimit` module by mholt doesn't have a direct burst parameter. Consider:
+>
+> 1. Using a sliding window algorithm (already default)
+> 2. Implementing burst via separate zone for initial requests
+> 3. Document limitation in UI
+
+##### 2.2.2 Add Bypass List Support
+
+**File:** `backend/internal/models/security_config.go`
+
+```go
+type SecurityConfig struct {
+ // ... existing fields ...
+ RateLimitBypassList string `json:"rate_limit_bypass_list" gorm:"type:text"` // Comma-separated CIDRs
+}
+```
+
+**File:** `backend/internal/caddy/config.go`
+
+```go
+func buildRateLimitHandler(host *models.ProxyHost, secCfg *models.SecurityConfig) (Handler, error) {
+ // ... existing validation ...
+
+ h := Handler{"handler": "rate_limit"}
+
+ // Build zone configuration
+ zone := map[string]interface{}{
+  "key":        "{http.request.remote.host}",
+  "window":     fmt.Sprintf("%ds", secCfg.RateLimitWindowSec),
+  "max_events": secCfg.RateLimitRequests,
+ }
+
+ h["rate_limits"] = map[string]interface{}{"static": zone}
+
+ // If bypass list is configured, wrap in a subroute that skips for those IPs
+ if secCfg.RateLimitBypassList != "" {
+  bypassCIDRs := parseBypassList(secCfg.RateLimitBypassList)
+  if len(bypassCIDRs) > 0 {
+   return Handler{
+    "handler": "subroute",
+    "routes": []map[string]interface{}{
+     {
+      // Skip rate limiting for bypass IPs
+      "match": []map[string]interface{}{
+       {"remote_ip": map[string]interface{}{"ranges": bypassCIDRs}},
+      },
+      "terminal": false, // Continue to proxy handler
+     },
+     {
+      // Apply rate limiting for all others
+      "handle": []Handler{h},
+     },
+    },
+   }, nil
+  }
+ }
+
+ return h, nil
+}
+
+#### 2.3 Rate Limiting — Test Plan (Detailed)
+
+**Summary:** This section contains a complete test plan to validate rate limiting configuration generation and runtime enforcement in Charon. Tests are grouped into Unit, Integration and E2E categories and prioritize quick unit coverage and high-impact integration tests.
+
+Goal: Verify the following behavior:
+- The `RateLimitBurst`, `RateLimitRequests`, `RateLimitWindowSec` and `RateLimitBypassList` fields are used by `buildRateLimitHandler` and emitted into the Caddy JSON configuration.
+- The Caddy `rate_limit` handler configuration uses `{http.request.remote.host}` as the key.
+- Bypass IPs are excluded from rate limiting by creating a subroute with `remote_ip` matcher.
+- At runtime, Caddy enforces limits, returns `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `Retry-After` headers (or documented equivalents), and resets counters after the configured window.
+- The plugin behaves correctly across multiple client IPs and respects bypass lists.
+
+-----
+
+2.3.1 Files to Add / Edit
+- New scripts: `scripts/rate_limit_integration.sh` (shell integration test), `scripts/rate_limit_e2e.sh` (optional extended tests).
+- New integration test: `backend/integration/rate_limit_integration_test.go` (go test wrapper runs script).
+- Unit tests to add/edit: `backend/internal/caddy/config_test.go` (add `TestGenerateConfig_WithRateLimitBypassList` and `TestBuildRateLimitHandler_KeyIsRemoteHost`), `backend/internal/api/handlers/security_ratelimit_test.go` (validate API fields persist & UpdateConfig accepts rate_limit fields).
+
+2.3.2 Unit Tests (fast, run in CI pre-merge)
+- File: `backend/internal/caddy/config_test.go`
+ - `TestGenerateConfig_WithRateLimitBypassList`
+  - Input: call `GenerateConfig` with `secCfg` set with `RateLimitEnable:true` and `RateLimitBypassList:"10.0.0.0/8,127.0.0.1/32"`; include one host.
+  - Assertions:
+   - The generated `Config` contains a route with `handler:"subroute"` or a `rate_limit` handler containing the bypass CIDRs (CIDRs found in JSON output).
+   - `RateLimitHandler` contains `rate_limits` map and `static` zone.
+ - `TestBuildRateLimitHandler_KeyIsRemoteHost`
+  - Input: `secCfg` with valid values.
+  - Assertions: the static zone `key` is `{http.request.remote.host}`.
+ - `TestBuildRateLimitHandler_DefaultBurstAndMax` (already present) and `TestParseBypassCIDRs` (existing) remain required.
+
+2.3.3 Integration Tests (CI gated, Docker required)
+We will add a scripted integration test to run inside CI or locally with Docker. The test will:
+ - Start the `charon:local` image (build if not present) in a detached container named `charon-debug`.
+ - Create a simple HTTP backend (httpbin/kennethreitz/httpbin) called `ratelimit-backend` (or `httpbin`).
+ - Create a proxy host `ratelimit.local` pointing to the backend via the Charon API (use /api/v1/proxy-hosts).
+ - Set `SecurityConfig` (POST /api/v1/security/config) with short windows for speed, e.g.:
+  ```json
+  {"name":"default","enabled":true,"rate_limit_enable":true,"rate_limit_requests":3,"rate_limit_window_sec":10,"rate_limit_burst":1}
+  ```
+ - Validate that Caddy Admin API at `http://localhost:2019/config` includes a `rate_limit` handler and, where applicable, a `subroute` with bypass CIDRs (if `RateLimitBypassList` set).
+ - Execute the runtime checks:
+  - Using a single client IP, send 3 requests in quick succession expecting HTTP 200.
+  - The 4th request (same client IP) should return HTTP 429 (Too Many Requests) and include a `Retry-After` header.
+  - On allowed responses, assert that `X-RateLimit-Limit` equals 3 and `X-RateLimit-Remaining` decrements.
+  - Wait until the configured `RateLimitWindowSec` elapses, and confirm requests are allowed again (headers reset).
+
+ - Bypass List Validation:
+  - Set `RateLimitBypassList` to contain the requester's IP (or `127.0.0.1/32` when client runs from the host). Confirm repeated requests do not get `429`, and `X-RateLimit-*` headers may be absent or indicate non-enforcement.
+
+ - Multi-IP Isolation:
+  - Spin up two client containers with different IPs (via Docker network `--subnet` + `--ip`). Each should have independent counters; both able to make configured number requests without affecting the other.
+
+ - X-Forwarded-For behavior (Confirm remote.host is used as key):
+  - Send requests with `X-Forwarded-For` different than the container IP; observe rate counters still use the connection IP unless Caddy remote_ip plugin explicitly configured to respect XFF.
+
+ - Test Example (Shell Snippet to assert headers)
+  ```bash
+  # Single request driver - check headers
+  curl -s -D - -o /dev/null -H "Host: ratelimit.local" http://localhost/post
+  # Expect headers: X-RateLimit-Limit: 3, X-RateLimit-Remaining: <number>
+  ```
+
+ - Script name: `scripts/rate_limit_integration.sh` (mirrors style of `coraza_integration.sh`).
+
+ - Manage flaky behavior:
+  - Retry a couple times and log Caddy admin API output on failure for debugging.
++
+2.3.4 E2E Tests (Longer, optional)
+- Create `scripts/rate_limit_e2e.sh` which spins up the same environment but runs broader scenarios:
+ - High-rate bursts (WindowSec small and Requests small) to test burst allowance/consumption.
+ - Multi-minute stress run (not for every CI pass) to check long-term behavior and reset across windows.
+ - SPA / browser test using Playwright / Cypress to validate UI controls (admin toggles rate limit presets and sets bypass list) and ensures that applied config is effective at runtime.
+
+2.3.5 Mock/Stub Guidance
+- IP Addresses
+ - Use Docker network subnets and `docker run --network containers_default --ip 172.25.0.10` to guarantee client IP addresses for tests and to exercise bypass list behavior.
+ - For tests run from host with `curl`, include `--interface` or `--local-port` if needed to force source IP (less reliable than container-based approach).
+- X-Forwarded-For
+ - Add `-H "X-Forwarded-For: 10.0.0.5"` to `curl` requests; assert that plugin uses real connection IP by default. If future changes enable `real_ip` handling in Caddy, tests should be updated to reflect the new behavior.
+- Timing Windows
+ - Keep small values (2-10 seconds) while maintaining reliability (1s windows are often flaky). For CI environment, `RateLimitWindowSec=10` with `RateLimitRequests=3` and `Burst=1` is a stable, fast choice.
+
+2.3.6 Test Data and Assertions (Explicit)
+- Unit Test: `TestBuildRateLimitHandler_ValidConfig`
+ - Input: secCfg{Requests:100, WindowSec:60, Burst:25}
+ - Assert: `h["handler"] == "rate_limit"`, `static".max_events == 100`, `burst == 25`.
+
+- Integration Test: `TestRateLimit_Enforcement_Basic`
+ - Input: RateLimitRequests=3, RateLimitWindowSec=10, Burst=1, no bypass list
+ - Actions: Send 4 rapid requests using client container
+ - Expected outputs: [200, 200, 200, 429], 4th returns Retry-After or explicit block message
+ - Assert: Allowed responses include `X-RateLimit-Limit: 3`, and `X-RateLimit-Remaining` decreasing
+
+- Integration Test: `TestRateLimit_BypassList_SkipsLimit`
+ - Input: Same as above + `RateLimitBypassList` contains client IP CIDR
+ - Expected outputs: All requests 200 (no 429)
+
+- Integration Test: `TestRateLimit_MultiClient_Isolation`
+ - Input: As above
+ - Actions: Client A sends 3 requests, Client B sends 3 requests
+ - Expected: Both clients unaffected by the other; both get 200 responses for their first 3 requests
+
+- Integration Test: `TestRateLimit_Window_Reset`
+ - Input: As above
+ - Actions: Exhaust quota (get 429), wait `RateLimitWindowSec + 1`, issue a new request
+ - Expected: New request is 200 again
+
+2.3.7 Test Harness - Example Go Integration Test
+Use the same approach as `backend/integration/coraza_integration_test.go`, run the script and check output for expected messages. Example test file: `backend/integration/rate_limit_integration_test.go`:
+
+```go
+//go:build integration
+// +build integration
+
+package integration
+
+import (
+  "context"
+  "os/exec"
+  "strings"
+  "testing"
+  "time"
+)
+
+func TestRateLimitIntegration(t *testing.T) {
+  t.Parallel()
+  ctx, cancel := context.WithTimeout(context.Background(), 10*time.Minute)
+  defer cancel()
+  cmd := exec.CommandContext(ctx, "bash", "./scripts/rate_limit_integration.sh")
+  out, err := cmd.CombinedOutput()
+  t.Logf("rate_limit_integration script output:\n%s", string(out))
+  if err != nil {
+    t.Fatalf("rate_limit integration failed: %v", err)
+  }
+  if !strings.Contains(string(out), "Rate limit enforcement succeeded") {
+    t.Fatalf("unexpected script output, rate limiting assertion not found")
+  }
+}
+```
+
+2.3.8 CI and Pre-commit Hooks
+
+- Add an integration CI job that runs the Docker-based script and the integration `go` test suite in a separate job to avoid blocking unit test runs on tools requiring Docker. Use a job matrix with `services: docker` and timeouts set appropriately.
+- Do not add integration scripts to pre-commit (too heavy); keep pre-commit focused on `go fmt`, `go vet`, `go test ./...` (unit tests), `npm test`, and lint rules.
+- Use the workspace `tasks.json` to add a `Coraza: Run Integration Script` style task for rate limit integration that mirrors `scripts/coraza_integration.sh`.
+
+2.3.9 .gitignore / .codecov.yml / Dockerfile changes
+
+- .gitignore
+ 	- Add `test-results/rate_limit/` to avoid committing local script logs.
+ 	- Add `scripts/rate_limit_integration.sh` output files (if any) to ignore.
+- .codecov.yml
+ 	- Optional: If you want integration test coverage included, remove `**/integration/**` from `ignore` or add a specific `backend/integration/*_test.go` to be included. (Caveat: integration coverage may not be reproducible across CI).
+- .dockerignore
+ 	- Ensure `scripts/` and `backend/integration` are not copied to reduce build context size if not needed in Docker build.
+- Dockerfile
+ 	- Confirm presence of `--with github.com/mholt/caddy-ratelimit` in the xcaddy build (it is present in base Dockerfile). Add comment and assert plugin presence in integration script by checking `caddy version` or `caddy list` available modules.
+
+2.3.10 Prioritization
+
+- P0: Integration test `TestRateLimit_Enforcement_Basic` (high confidence: verifies actual runtime limit enforcement and header presence)
+- P1: Unit tests verifying config building (`TestGenerateConfig_WithRateLimitBypassList`, `TestBuildRateLimitHandler_KeyIsRemoteHost`) and API tests for `POST /security/config` handling rate limit fields
+- P2: Integration tests for bypass list, multi-client isolation, window reset
+- P3: E2E tests for UI configuration of rate limiting and long-running stress tests
+
+2.3.11 Next Steps
+
+- Implement `scripts/rate_limit_integration.sh` and `backend/integration/rate_limit_integration_test.go` following `coraza_integration.sh` as the blueprint.
+- Add unit tests to `backend/internal/caddy/config_test.go` and API handler tests in `backend/internal/api/handlers/security_ratelimit_test.go`.
+- Add Docker network helpers and ensure `docker run --ip` is used to control client IPs during integration.
+- Run all new tests locally (Docker required) and in CI. Add integration job to GitHub Actions with `runs-on: ubuntu-latest`, `services: docker` and appropriate timeouts.
+
+-----
+
+This test plan should serve as a complete specification for testing rate limiting behavior across unit, integration, and E2E tiers. The next iteration will include scripted test implementations and Jenkins/GHA job snippets for CI.

+
+##### 2.2.3 Add Preset Templates
+
+**File:** `backend/internal/api/handlers/security_handler.go`
+
+```go
+// GetRateLimitPresets returns predefined rate limit configurations
+func (h *SecurityHandler) GetRateLimitPresets(c *gin.Context) {

+   "burst":       100,
+  },
+ }
+ c.JSON(http.StatusOK, gin.H{"presets": presets})
+}
+```
+
+**Add route:** `GET /api/v1/security/rate-limit/presets`
+
+##### 2.2.4 Frontend Updates
+
+**File:** `frontend/src/api/security.ts`
+
+```typescript
+export interface RateLimitPreset {
+  id: string
+  name: string
+  description: string
+  requests: number
+  window_sec: number
+  burst: number
+}
+
+export const getRateLimitPresets = async (): Promise<{ presets: RateLimitPreset[] }> => {
+  const response = await client.get('/security/rate-limit/presets')
+  return response.data
+}
+```
+
+**File:** `frontend/src/pages/RateLimiting.tsx`
+
+Add preset dropdown and bypass list input (see implementation details in frontend section below).
+
+#### 2.3 Test Requirements
+
+**File:** `backend/internal/caddy/config_test.go`
+
+```go
+func TestBuildRateLimitHandler_UsesBurst(t *testing.T) {
+ secCfg := &models.SecurityConfig{
+  RateLimitRequests:  100,
+  RateLimitWindowSec: 60,
+  RateLimitBurst:     25,
+ }
+ h, err := buildRateLimitHandler(nil, secCfg)
+ require.NoError(t, err)

+ }
+ h, err := buildRateLimitHandler(nil, secCfg)
+ require.NoError(t, err)
+ // Verify subroute structure with bypass
+}
+```
+

+
+### Phase 3: CrowdSec Bouncer (Issue #17)
+
+**Goal:** Implement actual IP reputation checking against CrowdSec decisions.
+
+#### 3.1 Current State Analysis
+
+- CrowdSec binary installed in Docker image
+- `caddy-crowdsec-bouncer` plugin compiled into Caddy
+- `buildCrowdSecHandler` returns a handler but only sets `api_url`
+- Comment in `cerberus.go`: "CrowdSec placeholder: integration would check CrowdSec API"
+- No actual decision lookup code
+
+#### 3.2 Architecture Decision
+
+**Two approaches:**
+
+| Approach | Pros | Cons |
+|----------|------|------|
+| **A: Caddy Plugin** | Offloads to Caddy, less Go code | Requires Caddy config regeneration |
+| **B: Middleware** | Real-time, Go-native | Duplicates bouncer logic |
+
+**Recommendation:** Use **Approach A** (Caddy Plugin) since `caddy-crowdsec-bouncer` is already compiled in. Enhance the handler configuration.
+
+#### 3.3 Required Changes
+
+##### 3.3.1 Update CrowdSec Handler Builder
+
+**File:** `backend/internal/caddy/config.go`
+
+```go
+// buildCrowdSecHandler returns a CrowdSec bouncer handler.
+// See: https://github.com/hslatman/caddy-crowdsec-bouncer
+func buildCrowdSecHandler(host *models.ProxyHost, secCfg *models.SecurityConfig, crowdsecEnabled bool) (Handler, error) {
+ if !crowdsecEnabled {
+  return nil, nil
+ }
+
+ h := Handler{"handler": "crowdsec"}
+
+ // API URL (required)
+ apiURL := "http://localhost:8080"
+ if secCfg != nil && secCfg.CrowdSecAPIURL != "" {
+  apiURL = secCfg.CrowdSecAPIURL
+ }
+ h["api_url"] = apiURL
+
+ // API Key (from environment or config)
+ apiKey := os.Getenv("CROWDSEC_API_KEY")
+ if apiKey == "" && secCfg != nil {
+  // Could store encrypted in DB - for now use env var
+ }
+ if apiKey != "" {
+  h["api_key"] = apiKey
+ }
+
+ // Ticker interval for decision sync (default 30s)
+ h["ticker_interval"] = "30s"
+
+ // Enable streaming mode for real-time updates
+ h["enable_streaming"] = true
+
+ return h, nil
+}
+```
+
+##### 3.3.2 Add CrowdSec Registration on Startup
+
+**File:** `backend/internal/crowdsec/registration.go` (new)
+
+```go
+// Package crowdsec handles CrowdSec LAPI integration.
+package crowdsec
+
+import (
+ "bytes"
+ "encoding/json"
+ "fmt"
+ "net/http"
+ "os"
+ "os/exec"
+ "time"
+)
+
+// EnsureBouncerRegistered registers the Caddy bouncer with local CrowdSec LAPI.
+func EnsureBouncerRegistered(lapiURL string) (string, error) {
+ // Check if already registered
+ apiKey := os.Getenv("CROWDSEC_API_KEY")
+ if apiKey != "" {
+  return apiKey, nil
+ }
+
+ // Use cscli to register bouncer
+ cmd := exec.Command("cscli", "bouncers", "add", "caddy-bouncer", "-o", "raw")
+ output, err := cmd.Output()
+ if err != nil {
+  // May already exist, try to get existing key
+  return "", fmt.Errorf("failed to register bouncer: %w", err)
+ }
+
+ apiKey = string(bytes.TrimSpace(output))
+ return apiKey, nil
+}
+
+// CheckLAPIHealth verifies CrowdSec LAPI is responding.
+func CheckLAPIHealth(lapiURL string) bool {
+ client := &http.Client{Timeout: 5 * time.Second}
+ resp, err := client.Get(lapiURL + "/v1/decisions")
+ if err != nil {
+  return false
+ }
+ defer resp.Body.Close()
+ // 401 is expected without auth, but means LAPI is up
+ return resp.StatusCode == 401 || resp.StatusCode == 200
+}
+```
+
+##### 3.3.3 Update Cerberus Middleware (Optional - for logging)
+
+**File:** `backend/internal/cerberus/cerberus.go`
+
+The actual blocking is handled by the Caddy CrowdSec bouncer plugin. However, we can add logging in Cerberus:
+
+```go
+// In Middleware(), after ACL check:
+// CrowdSec logging (actual blocking is done by Caddy bouncer)
+if c.cfg.CrowdSecMode == "local" {
+ // Log that CrowdSec is active (blocking happens at Caddy layer)
+ logger.Log().WithField("client_ip", ctx.ClientIP()).Debug("Request evaluated by CrowdSec bouncer")
+}
+```
+
+##### 3.3.4 Add CrowdSec Status Endpoint Enhancement
+
+**File:** `backend/internal/api/handlers/crowdsec_handler.go`
+
+```go
+// GetCrowdSecDecisions returns recent decisions from CrowdSec LAPI
+func (h *CrowdSecHandler) GetDecisions(c *gin.Context) {
+ lapiURL := os.Getenv("CROWDSEC_LAPI_URL")
+ if lapiURL == "" {
+  lapiURL = "http://localhost:8080"
+ }
+
+ apiKey := os.Getenv("CROWDSEC_API_KEY")
+ if apiKey == "" {
+  c.JSON(http.StatusServiceUnavailable, gin.H{"error": "CrowdSec API key not configured"})
+  return
+ }
+
+ client := &http.Client{Timeout: 10 * time.Second}
+ req, _ := http.NewRequest("GET", lapiURL+"/v1/decisions", nil)
+ req.Header.Set("X-Api-Key", apiKey)
+
+ resp, err := client.Do(req)
+ if err != nil {
+  c.JSON(http.StatusBadGateway, gin.H{"error": "Failed to connect to CrowdSec LAPI"})
+  return
+ }
+ defer resp.Body.Close()
+
+ var decisions []map[string]interface{}
+ json.NewDecoder(resp.Body).Decode(&decisions)
+ c.JSON(http.StatusOK, gin.H{"decisions": decisions})
+}
+```
+
+#### 3.4 Frontend Updates
+
+**File:** `frontend/src/pages/CrowdSecConfig.tsx`
+
+Add decisions viewer panel:
+
+```tsx
+// In CrowdSecConfig component:
+const { data: decisions } = useQuery({
+  queryKey: ['crowdsec-decisions'],
+  queryFn: () => client.get('/api/v1/crowdsec/decisions').then(r => r.data),
+  enabled: status?.crowdsec?.enabled,
+  refetchInterval: 30000,
+})
+
+// Render decisions table
+{decisions?.decisions?.length > 0 && (
+  <Card>
+    <h3>Active Decisions</h3>
+    <table>
+      <thead>
+        <tr>
+          <th>IP/Range</th>
+          <th>Type</th>
+          <th>Reason</th>
+          <th>Expires</th>
+        </tr>
+      </thead>
+      <tbody>
+        {decisions.decisions.map((d: Decision) => (
+          <tr key={d.id}>
+            <td>{d.value}</td>
+            <td>{d.type}</td>
+            <td>{d.scenario}</td>
+            <td>{formatExpiry(d.until)}</td>
+          </tr>
+        ))}
+      </tbody>
+    </table>
+  </Card>
+)}
+```
+
+#### 3.5 Test Requirements
+
+**File:** `backend/internal/crowdsec/registration_test.go`
+
+```go
+func TestCheckLAPIHealth(t *testing.T) {
+ // Mock server test
+ ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+  w.WriteHeader(http.StatusUnauthorized) // Expected without auth
+ }))
+ defer ts.Close()
+
+ assert.True(t, CheckLAPIHealth(ts.URL))
+}
+```
+
+---
+
+### Phase 4: WAF Integration (Issue #18) - Most Complex
+
+**Goal:** Generate actual Coraza configuration, per-host toggle, rule exclusions, paranoia levels.
+
+#### 4.1 Current State Analysis
+
+- `cerberus.go` only checks for literal `<script>` string in URL (trivial bypass)
+- `buildWAFHandler` in `config.go` creates Coraza handler but requires ruleset
+- Frontend (`WafConfig.tsx`) manages rule sets but no per-host toggle
+- No paranoia level selector
+- No rule exclusion system for false positives
+
+#### 4.2 Required Changes
+
+##### 4.2.1 Enhance WAF Handler Builder
+
+**File:** `backend/internal/caddy/config.go`
+
+```go
+// buildWAFHandler returns a WAF handler (Coraza) configuration.
+func buildWAFHandler(host *models.ProxyHost, rulesets []models.SecurityRuleSet, rulesetPaths map[string]string, secCfg *models.SecurityConfig, wafEnabled bool) (Handler, error) {
+ if !wafEnabled {
+  return nil, nil
+ }
+
+ // Check per-host WAF toggle
+ if host != nil && host.WAFDisabled {
+  return nil, nil
+ }
+
+ // Build directives
+ var directives strings.Builder
+
+ // Base configuration
+ directives.WriteString("SecRuleEngine On\n")
+ directives.WriteString("SecRequestBodyAccess On\n")
+ directives.WriteString("SecResponseBodyAccess Off\n")
+
+ // Paranoia level (1-4, default 1)
+ paranoiaLevel := 1
+ if secCfg != nil && secCfg.WAFParanoiaLevel > 0 && secCfg.WAFParanoiaLevel <= 4 {
+  paranoiaLevel = secCfg.WAFParanoiaLevel
+ }
+ directives.WriteString(fmt.Sprintf("SecAction \"id:900000,phase:1,nolog,pass,t:none,setvar:tx.paranoia_level=%d\"\n", paranoiaLevel))
+
+ // Mode: block or monitor
+ if secCfg != nil && secCfg.WAFMode == "monitor" {
+  directives.WriteString("SecRuleEngine DetectionOnly\n")
+ }
+
+ // Include ruleset files
+ for _, rs := range rulesets {
+  if path, ok := rulesetPaths[rs.Name]; ok && path != "" {
+   directives.WriteString(fmt.Sprintf("Include %s\n", path))
+  }
+ }
+
+ // Apply exclusions
+ if secCfg != nil && secCfg.WAFExclusions != "" {
+  var exclusions []WAFExclusion
+  if err := json.Unmarshal([]byte(secCfg.WAFExclusions), &exclusions); err == nil {
+   for _, ex := range exclusions {
+    // Generate SecRuleRemoveById or SecRuleUpdateTargetById
+    if ex.RuleID > 0 {
+     if ex.Target != "" {
+      directives.WriteString(fmt.Sprintf("SecRuleUpdateTargetById %d \"!%s\"\n", ex.RuleID, ex.Target))
+     } else {
+      directives.WriteString(fmt.Sprintf("SecRuleRemoveById %d\n", ex.RuleID))
+     }
+    }
+   }
+  }
+ }
+
+ h := Handler{
+  "handler":    "waf",
+  "directives": directives.String(),
+ }
+
+ return h, nil
+}
+
+// WAFExclusion represents a rule exclusion for false positives
+type WAFExclusion struct {
+ RuleID      int    `json:"rule_id"`
+ Target      string `json:"target,omitempty"`       // e.g., "ARGS:password"
+ Description string `json:"description,omitempty"`
+}
+```
+
+##### 4.2.2 Add Per-Host WAF Toggle
+
+**File:** `backend/internal/models/proxy_host.go`
+
+```go
+type ProxyHost struct {
+ // ... existing fields ...
+ WAFDisabled bool `json:"waf_disabled" gorm:"default:false"` // Override global WAF
+}
+```
+
+##### 4.2.3 Add Paranoia Level and Exclusions to SecurityConfig
+
+**File:** `backend/internal/models/security_config.go`
+
+```go
+type SecurityConfig struct {
+ // ... existing fields ...
+ WAFParanoiaLevel int    `json:"waf_paranoia_level" gorm:"default:1"` // 1-4
+ WAFExclusions    string `json:"waf_exclusions" gorm:"type:text"`     // JSON array of exclusions
+}
+```
+
+##### 4.2.4 Remove Naive Check from Cerberus Middleware
+
+**File:** `backend/internal/cerberus/cerberus.go`
+
+The current `<script>` check is misleading. Replace with proper logging:
+
+```go
+// WAF is handled by Coraza at the Caddy layer
+// Log WAF status for debugging
+if c.cfg.WAFMode != "" && c.cfg.WAFMode != "disabled" {
+ logger.Log().WithFields(map[string]interface{}{
+  "source":    "waf",
+  "mode":      c.cfg.WAFMode,
+  "client_ip": ctx.ClientIP(),
+ }).Debug("Request subject to WAF inspection")
+}
+```
+
+##### 4.2.5 Add Rule Exclusion Management Endpoints
+
+**File:** `backend/internal/api/handlers/security_handler.go`
+
+```go
+// GetWAFExclusions returns current WAF rule exclusions
+func (h *SecurityHandler) GetWAFExclusions(c *gin.Context) {
+ cfg, err := h.svc.Get()
+ if err != nil && err != services.ErrSecurityConfigNotFound {
+  c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to get config"})
+  return
+ }
+
+ var exclusions []WAFExclusion
+ if cfg != nil && cfg.WAFExclusions != "" {
+  json.Unmarshal([]byte(cfg.WAFExclusions), &exclusions)
+ }
+ c.JSON(http.StatusOK, gin.H{"exclusions": exclusions})
+}
+
+// AddWAFExclusion adds a rule exclusion
+func (h *SecurityHandler) AddWAFExclusion(c *gin.Context) {
+ var exclusion WAFExclusion
+ if err := c.ShouldBindJSON(&exclusion); err != nil {
+  c.JSON(http.StatusBadRequest, gin.H{"error": "Invalid payload"})
+  return
+ }
+
+ cfg, _ := h.svc.Get()
+ if cfg == nil {
+  cfg = &models.SecurityConfig{Name: "default"}
+ }
+
+ var exclusions []WAFExclusion
+ if cfg.WAFExclusions != "" {
+  json.Unmarshal([]byte(cfg.WAFExclusions), &exclusions)
+ }
+
+ exclusions = append(exclusions, exclusion)
+ data, _ := json.Marshal(exclusions)
+ cfg.WAFExclusions = string(data)
+
+ if err := h.svc.Upsert(cfg); err != nil {
+  c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to save"})
+  return
+ }
+
+ // Apply to Caddy
+ if h.caddyManager != nil {
+  h.caddyManager.ApplyConfig(c.Request.Context())
+ }
+
+ c.JSON(http.StatusOK, gin.H{"exclusion": exclusion})
+}
+```
+
+**Routes:**
+
+- `GET /api/v1/security/waf/exclusions`
+- `POST /api/v1/security/waf/exclusions`
+- `DELETE /api/v1/security/waf/exclusions/:id`
+
+#### 4.3 Frontend Updates
+
+##### 4.3.1 Update WafConfig Page
+
+**File:** `frontend/src/pages/WafConfig.tsx`
+
+Add:
+
+1. Paranoia level selector (1-4 with descriptions)
+2. Exclusions management panel
+3. Per-host override indicator
+
+```tsx
+// Paranoia level selector
+const PARANOIA_LEVELS = [
+  { level: 1, name: 'Low', description: 'Minimal false positives, basic protection' },
+  { level: 2, name: 'Medium', description: 'Balanced protection, some false positives' },
+  { level: 3, name: 'High', description: 'Strong protection, requires tuning' },
+  { level: 4, name: 'Paranoid', description: 'Maximum protection, many false positives' },
+]
+
+// In render:
+<div>
+  <label>Paranoia Level</label>
+  <select value={paranoiaLevel} onChange={...}>
+    {PARANOIA_LEVELS.map(p => (
+      <option key={p.level} value={p.level}>
+        {p.level} - {p.name}
+      </option>
+    ))}
+  </select>
+  <p className="text-xs text-gray-500">
+    {PARANOIA_LEVELS.find(p => p.level === paranoiaLevel)?.description}
+  </p>
+</div>
+```
+
+##### 4.3.2 Add Per-Host WAF Toggle to Proxy Host Form
+
+**File:** `frontend/src/pages/ProxyHostForm.tsx` (or similar)
+
+```tsx
+<Switch
+  label="Disable WAF for this host"
+  checked={formData.waf_disabled}

+
+## Implementation Order
+
+1. **Phase 2 (Rate Limit)** - Quickest, enables immediate value
+2. **Phase 1 (GeoIP)** - Most user-requested feature
+3. **Phase 4 (WAF)** - Most complex but highest security impact
+4. **Phase 3 (CrowdSec)** - Requires external service coordination
+
+---
+
+## Definition of Done Checklist
+
+For each phase:
+
+- [ ] All new code has unit tests with >85% coverage
+- [ ] Pre-commit hooks pass (`pre-commit run --all-files`)
+- [ ] Backend compiles without warnings (`go build ./...`)
+- [ ] Frontend builds without errors (`npm run build`)
+- [ ] Integration tests pass (if applicable)
+- [ ] Documentation updated in `docs/cerberus.md`
+- [ ] API changes reflected in `docs/api.md`
+- [ ] Feature documented in `docs/features.md`
+

+
+## Risk Assessment
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| GeoIP database missing | Geo-blocking fails silently | Graceful fallback with warning |
+| CrowdSec LAPI unavailable | No IP reputation | Caddy continues without bouncer |
+| WAF exclusions break rules | Security gap | Validate rule IDs, log exclusions |
+| Rate limit bypass abused | DDoS possible | Audit bypass list, alert on changes |

-# Cerberus Security Module - Comprehensive Remediation Plan
+# CI Docker Build Failure - Root Cause Analysis and Remediation Plan
 
-**Version:** 2.0
-**Date:** 2025-12-12
-**Status:** 🔴 PENDING - Issues #16, #17, #18, #19 incomplete
+**Version:** 1.0
+**Date:** 2025-12-14
+**Status:** 🔴 CRITICAL - Docker builds failing in CI
 
 ---
 
 ## Executive Summary
 
-This document provides a **comprehensive, actionable remediation plan** to complete the Cerberus security module. Four GitHub issues remain partially implemented:
+The CI Docker build is failing during the xcaddy build process. The root cause is a **Go version mismatch** introduced by a recent commit that downgraded Go from 1.25.x to 1.23.x based on the incorrect assumption that Go 1.25.5 doesn't exist.
 
-| Issue | Feature | Current State | Priority |
-|-------|---------|---------------|----------|
-| #16 | GeoIP Integration | Database downloaded, no Go code reads it | HIGH |
-| #17 | CrowdSec Bouncer | Placeholder comment in code | HIGH |
-| #18 | WAF (Coraza) Integration | Only checks `<script>` tag, no real Coraza config | HIGH |
-| #19 | Rate Limiting | Burst field unused, no bypass list/templates | MEDIUM |
+### Key Finding
+
+**Go 1.25.5 IS a valid, released version** (as of December 2025). The commit `481208c` ("fix: correct Go version to 1.23 in Dockerfile (1.25.5 does not exist)") incorrectly downgraded Go and **broke the build**.
 
 ---
 
-## Implementation Phases
+## Root Cause Analysis
 
-### Phase 1: GeoIP Integration (Issue #16)
+### 1. Version Compatibility Matrix (Current State)
 
-**Goal:** Enable actual IP → Country lookup for geo-blocking ACLs.
+| Component | Version Required | Version in Dockerfile | Status |
+|-----------|------------------|----------------------|--------|
+| **Go** (for Caddy build) | 1.25+ | 1.23 ❌ | **INCOMPATIBLE** |
+| **Go** (for backend build) | 1.23+ | 1.23 ✅ | Compatible |
+| **Caddy** | 2.10.2 | 2.10.2 ✅ | Correct |
+| **xcaddy** | 0.4.5 | latest ✅ | Correct |
 
-#### 1.1 Current State Analysis
+### 2. The Problem
 
-- **Dockerfile** downloads `GeoLite2-Country.mmdb` to `/app/data/geoip/`
-- **Environment variable** `CHARON_GEOIP_DB_PATH` is set
-- **No Go code** imports or reads the MaxMind database
-- **Caddy config** uses `caddy-geoip2` plugin with `{geoip2.country_code}` placeholder (works at proxy level)
-- **`TestIP` service method** only evaluates IP/CIDR rules, returns default for geo types
+Caddy 2.10.2's `go.mod` declares:
 
-#### 1.2 Required Changes
+```go
+go 1.25
+```
 
-##### 1.2.1 Add GeoIP Dependency
+When xcaddy tries to build Caddy 2.10.2 with Go 1.23, it fails because:
 
-**File:** `backend/go.mod`
+- Go's toolchain directive enforcement (Go 1.21+) prevents building modules that require a newer Go version
+- The error manifests during the xcaddy build step in the Dockerfile
+
+### 3. Error Location
+
+**File:** [Dockerfile](../../Dockerfile)
+**Stage:** `caddy-builder` (lines 101-145)
+**Root Cause Lines:**
+
+- Line 51: `FROM --platform=$BUILDPLATFORM golang:1.23-alpine AS backend-builder`
+- Line 101: `FROM --platform=$BUILDPLATFORM golang:1.23-alpine AS caddy-builder`
+
+### 4. Evidence from go.mod Files
+
+**Caddy 2.10.2** (`github.com/caddyserver/caddy/v2`):
+
+```go
+go 1.25
+```
+
+**xcaddy 0.4.5** (`github.com/caddyserver/xcaddy`):
+
+```go
+go 1.21
+toolchain go1.23.0
+```
+
+**Backend** (`/projects/Charon/backend/go.mod`):
+
+```go
+go 1.23
+```
+
+**Workspace** (`/projects/Charon/go.work`):
+
+```go
+go 1.23
+```
+
+### 5. Plugin Compatibility
+
+| Plugin | Go Version Required | Caddy Version Tested |
+|--------|---------------------|---------------------|
+| caddy-security | 1.24 | v2.9.1 |
+| coraza-caddy/v2 | 1.23 | v2.9.1 |
+| caddy-crowdsec-bouncer | 1.23 | v2.9.1 |
+| caddy-geoip2 | varies | - |
+| caddy-ratelimit | varies | - |
+
+**Note:** Plugin compatibility with Caddy 2.10.2 requires Go 1.25 since Caddy itself requires it.
+
+---
+
+## Remediation Plan
+
+### Option A: Upgrade Go to 1.25 (RECOMMENDED)
+
+**Rationale:** Go 1.25.5 exists and is stable. Upgrading aligns with Caddy 2.10.2 requirements.
+
+#### File Changes Required
+
+##### 1. Dockerfile (lines 51, 101)
+
+**Current (BROKEN):**
+
+```dockerfile
+FROM --platform=$BUILDPLATFORM golang:1.23-alpine AS backend-builder
+...
+FROM --platform=$BUILDPLATFORM golang:1.23-alpine AS caddy-builder
+```
+
+**Fix:**
+
+```dockerfile
+FROM --platform=$BUILDPLATFORM golang:1.25-alpine AS backend-builder
+...
+FROM --platform=$BUILDPLATFORM golang:1.25-alpine AS caddy-builder
+```
+
+##### 2. backend/go.mod (line 3)
+
+**Current:**
+
+```go
+go 1.23
+```
+
+**Fix:**
+
+```go
+go 1.25
+```
+
+##### 3. go.work (line 1)
+
+**Current:**
+
+```go
+go 1.23
+```
+
+**Fix:**
+
+```go
+go 1.25
+```
+
+---
+
+### Option B: Downgrade Caddy to 2.9.x (NOT RECOMMENDED)
+
+**Rationale:** Would require pinning to an older Caddy version that still supports Go 1.23.
+
+**Downsides:**
+
+- Miss security fixes in Caddy 2.10.x
+- Need to update `CADDY_VERSION` ARG
+- Still need to verify plugin compatibility
+
+**File Changes:**
+
+```dockerfile
+ARG CADDY_VERSION=2.9.1  # Downgrade from 2.10.2
+```
+
+**Not recommended** because it's a regression and delays inevitable Go upgrade.
+
+---
+
+## Recommended Implementation: Option A
+
+### Step-by-Step Remediation
+
+#### Step 1: Update Dockerfile
+
+**File:** [Dockerfile](../../Dockerfile)
+
+| Line | Current | New |
+|------|---------|-----|
+| 51 | `golang:1.23-alpine` | `golang:1.25-alpine` |
+| 101 | `golang:1.23-alpine` | `golang:1.25-alpine` |
+
+#### Step 2: Update go.mod
+
+**File:** [backend/go.mod](../../backend/go.mod)
+
+| Line | Current | New |
+|------|---------|-----|
+| 3 | `go 1.23` | `go 1.25` |
+
+Then run:
 
 ```bash
-cd backend && go get github.com/oschwald/geoip2-golang
+cd backend && go mod tidy
 ```
 
-##### 1.2.2 Create GeoIP Service
+#### Step 3: Update go.work
 
-**New File:** `backend/internal/services/geoip_service.go`
+**File:** [go.work](../../go.work)
 
-```go
-// Package services provides business logic for the application.
-package services
+| Line | Current | New |
+|------|---------|-----|
+| 1 | `go 1.23` | `go 1.25` |
 
-import (
- "errors"
- "net"
- "sync"
+#### Step 4: Verify Local Build
 
- "github.com/oschwald/geoip2-golang"
-)
+```bash
+# Build Docker image locally
+docker build -t charon:test .
 
-var (
- ErrGeoIPDatabaseNotLoaded = errors.New("geoip database not loaded")
- ErrInvalidIP              = errors.New("invalid IP address")
- ErrCountryNotFound        = errors.New("country not found for IP")
-)
-
-// GeoIPService provides IP-to-country lookups using MaxMind GeoLite2.
-type GeoIPService struct {
- mu     sync.RWMutex
- db     *geoip2.Reader
- dbPath string
-}
-
-// NewGeoIPService creates a new GeoIPService and loads the database.
-func NewGeoIPService(dbPath string) (*GeoIPService, error) {

- s.mu.RLock()
- defer s.mu.RUnlock()
- return s.db != nil
-}
+# Run the test suite
+cd backend && go test ./...
+cd frontend && npm run test
 ```
 
-##### 1.2.3 Update AccessListService to Use GeoIP
+#### Step 5: Validate CI Workflows
 
-**File:** `backend/internal/services/access_list_service.go`
+The following workflows use Go and will automatically use the container's Go version:
 
-**Add field to struct:**
+- [docker-build.yml](../../.github/workflows/docker-build.yml) - Uses Dockerfile Go version
+- [docker-publish.yml](../../.github/workflows/docker-publish.yml) - Uses Dockerfile Go version
+- [quality-checks.yml](../../.github/workflows/quality-checks.yml) - May need `go-version` update
 
-```go
-type AccessListService struct {
- db       *gorm.DB
- geoipSvc *GeoIPService  // NEW
-}
-```
-
-**Update constructor:**
-
-```go
-func NewAccessListService(db *gorm.DB) *AccessListService {
- return &AccessListService{
-  db:       db,
-  geoipSvc: nil, // Will be set via SetGeoIPService
- }
-}
-
-// SetGeoIPService attaches a GeoIP service for country lookups.
-func (s *AccessListService) SetGeoIPService(geoipSvc *GeoIPService) {
- s.geoipSvc = geoipSvc
-}
-```
-
-**Update `TestIP` method to handle geo types:**
-
-```go
-// TestIP tests if an IP address would be allowed/blocked by the access list
-func (s *AccessListService) TestIP(aclID uint, ipAddress string) (allowed bool, reason string, err error) {
- acl, err := s.GetByID(aclID)
- if err != nil {
-  return false, "", err
- }
-
- if !acl.Enabled {
-  return true, "Access list is disabled - all traffic allowed", nil
- }
-
- ip := net.ParseIP(ipAddress)
- if ip == nil {
-  return false, "", ErrInvalidIPAddress
- }
-
- // Handle geo-based ACLs
- if strings.HasPrefix(acl.Type, "geo_") {
-  if s.geoipSvc == nil {
-   return true, "GeoIP service not available - allowing by default", nil
-  }
-
-  countryCode, err := s.geoipSvc.LookupCountry(ipAddress)
-  if err != nil {
-   // If lookup fails, allow with warning
-   return true, fmt.Sprintf("GeoIP lookup failed: %v - allowing by default", err), nil
-  }
-
-  // Parse country codes from ACL
-  allowedCodes := make(map[string]bool)
-  for _, code := range strings.Split(acl.CountryCodes, ",") {
-   allowedCodes[strings.TrimSpace(strings.ToUpper(code))] = true
-  }
-
-  isInList := allowedCodes[countryCode]
-
-  if acl.Type == "geo_whitelist" {
-   if isInList {
-    return true, fmt.Sprintf("Allowed by geo whitelist: IP from %s", countryCode), nil
-   }
-   return false, fmt.Sprintf("Blocked: IP from %s not in geo whitelist", countryCode), nil
-  }
-
-  // geo_blacklist
-  if isInList {
-   return false, fmt.Sprintf("Blocked by geo blacklist: IP from %s", countryCode), nil
-  }
-  return true, fmt.Sprintf("Allowed: IP from %s not in geo blacklist", countryCode), nil
- }
-
- // ... rest of existing IP/CIDR logic unchanged ...
-}
-```
-
-##### 1.2.4 Initialize GeoIP Service on Server Start
-
-**File:** `backend/internal/server/server.go` (or wherever services are initialized)
-
-```go
-import (
- "os"
- // ...
-)
-
-// In server initialization:
-geoipPath := os.Getenv("CHARON_GEOIP_DB_PATH")
-if geoipPath == "" {
- geoipPath = "/app/data/geoip/GeoLite2-Country.mmdb"
-}
-
-var geoipSvc *services.GeoIPService
-if _, err := os.Stat(geoipPath); err == nil {
- geoipSvc, err = services.NewGeoIPService(geoipPath)
- if err != nil {
-  logger.Log().WithError(err).Warn("Failed to load GeoIP database, geo-blocking will be unavailable")
- } else {
-  logger.Log().Info("GeoIP database loaded successfully")
- }
-}
-
-// Pass to AccessListService
-accessListSvc := services.NewAccessListService(db)
-if geoipSvc != nil {
- accessListSvc.SetGeoIPService(geoipSvc)
-}
-```
-
-##### 1.2.5 Add GeoIP Reload Endpoint (Optional Enhancement)
-
-**File:** `backend/internal/api/handlers/security_handler.go`
-
-```go
-// ReloadGeoIP reloads the GeoIP database from disk
-func (h *SecurityHandler) ReloadGeoIP(c *gin.Context) {
- if h.geoipSvc == nil {
-  c.JSON(http.StatusServiceUnavailable, gin.H{"error": "GeoIP service not initialized"})
-  return
- }
- if err := h.geoipSvc.Load(); err != nil {
-  c.JSON(http.StatusInternalServerError, gin.H{"error": fmt.Sprintf("Failed to reload: %v", err)})
-  return
- }
- c.JSON(http.StatusOK, gin.H{"message": "GeoIP database reloaded"})
-}
-```
-
-**Add route:** `POST /api/v1/security/geoip/reload`
-
-#### 1.3 Test Requirements
-
-**New File:** `backend/internal/services/geoip_service_test.go`
-
-```go
-func TestGeoIPService_LookupCountry(t *testing.T) {
- // Skip if no test database available
- testDBPath := os.Getenv("TEST_GEOIP_DB_PATH")
- if testDBPath == "" {
-  t.Skip("TEST_GEOIP_DB_PATH not set")
- }
-
- svc, err := NewGeoIPService(testDBPath)
- require.NoError(t, err)
- defer svc.Close()
-
- tests := []struct {
-  name    string
-  ip      string
-  wantCC  string
-  wantErr bool
- }{
-  {"Google DNS", "8.8.8.8", "US", false},
-  {"Cloudflare", "1.1.1.1", "AU", false}, // May vary
-  {"Invalid IP", "not-an-ip", "", true},
-  {"Private IP", "192.168.1.1", "", true}, // No country
- }
-
- for _, tt := range tests {
-  t.Run(tt.name, func(t *testing.T) {
-   cc, err := svc.LookupCountry(tt.ip)
-   if tt.wantErr {
-    assert.Error(t, err)
-   } else {
-    assert.NoError(t, err)
-    assert.Equal(t, tt.wantCC, cc)
-   }
-  })
- }
-}
-```
-
-**Update:** `backend/internal/services/access_list_service_test.go` - add tests for geo ACL `TestIP`.
-
-#### 1.4 Frontend Changes
-
-**File:** `frontend/src/pages/AccessLists.tsx`
-
-Update the test IP result display to show country code when geo-blocking:
-
-```tsx
-// In handleTestIP success callback:
-if (result.reason.includes("IP from")) {
-  toast.success(`${result.allowed ? '✅' : '🚫'} ${result.reason}`)
-} else {
-  // existing logic
-}
-```
-
-#### 1.5 Documentation Update
-
-**File:** `docs/cerberus.md` - Add section on GeoIP configuration and database updates.
+Check if `quality-checks.yml` specifies Go version explicitly and update if needed.
 
 ---
 
-### Phase 2: Rate Limit Fix (Issue #19) - Quick Win
+## Version Compatibility Matrix (After Fix)
 
-**Goal:** Fix burst field usage, add bypass list and preset templates.
+| Component | Version | Source |
+|-----------|---------|--------|
+| Go | 1.25 | Dockerfile, go.mod, go.work |
+| Caddy | 2.10.2 | Dockerfile ARG |
+| xcaddy | latest (0.4.5+) | go install |
+| Node.js | 24.12.0 | Dockerfile |
+| Alpine | 3.23 | Dockerfile |
 
-#### 2.1 Current State Analysis
+### Plugin Versions (auto-resolved by xcaddy)
 
-- `RateLimitBurst` field exists in `SecurityConfig` model
-- `buildRateLimitHandler` in `caddy/config.go` **ignores** burst field
-- No bypass list for trusted IPs
-- No preset templates (login, API, standard)
-- Frontend has burst input but it's not used by backend
+| Plugin | Current Version | Notes |
+|--------|-----------------|-------|
+| caddy-security | 1.1.31 | Works with Caddy 2.x |
+| coraza-caddy/v2 | 2.1.0 | Works with Caddy 2.x |
+| caddy-crowdsec-bouncer | main | Works with Caddy 2.x |
+| caddy-geoip2 | main | Works with Caddy 2.x |
+| caddy-ratelimit | main | Works with Caddy 2.x |
 
-#### 2.2 Required Changes
+---
 
-##### 2.2.1 Fix Burst Field in Caddy Config
+## Potential Side Effects
 
-**File:** `backend/internal/caddy/config.go`
+### 1. Backend Code Compatibility
 
-```go
-// buildRateLimitHandler returns a rate-limit handler using the caddy-ratelimit module.
-func buildRateLimitHandler(_ *models.ProxyHost, secCfg *models.SecurityConfig) (Handler, error) {
- if secCfg == nil {
-  return nil, nil
- }
- if secCfg.RateLimitRequests <= 0 || secCfg.RateLimitWindowSec <= 0 {
-  return nil, nil
- }
+Go 1.25 is backwards compatible with Go 1.23 code. The backend should compile without issues.
 
- // Calculate burst: if not set, default to 20% of requests
- burst := secCfg.RateLimitBurst
- if burst <= 0 {
-  burst = secCfg.RateLimitRequests / 5
-  if burst < 1 {
-   burst = 1
-  }
- }
+**Risk:** Low
+**Mitigation:** Run `go build ./...` and `go test ./...` after update.
 
- // caddy-ratelimit format with burst support
- h := Handler{"handler": "rate_limit"}
- h["rate_limits"] = map[string]interface{}{
-  "static": map[string]interface{}{
-   "key":        "{http.request.remote.host}",
-   "window":     fmt.Sprintf("%ds", secCfg.RateLimitWindowSec),
-   "max_events": secCfg.RateLimitRequests,
-   // NOTE: caddy-ratelimit doesn't have a direct "burst" param,
-   // but we can use distributed rate limiting or adjust max_events
-  },
- }
- return h, nil
-}
-```
+### 2. CI/CD Pipeline
 
-> **Note:** The `caddy-ratelimit` module by mholt doesn't have a direct burst parameter. Consider:
->
-> 1. Using a sliding window algorithm (already default)
-> 2. Implementing burst via separate zone for initial requests
-> 3. Document limitation in UI
+Some workflows may cache Go 1.23 artifacts. Force cache invalidation if builds fail after fix.
 
-##### 2.2.2 Add Bypass List Support
+**Risk:** Low
+**Mitigation:** Clear GitHub Actions cache if needed.
 
-**File:** `backend/internal/models/security_config.go`
+### 3. Local Development
 
-```go
-type SecurityConfig struct {
- // ... existing fields ...
- RateLimitBypassList string `json:"rate_limit_bypass_list" gorm:"type:text"` // Comma-separated CIDRs
-}
-```
+Developers using Go 1.23 locally will need to upgrade to Go 1.25.
 
-**File:** `backend/internal/caddy/config.go`
+**Risk:** Medium
+**Mitigation:** Document required Go version in README.md.
 
-```go
-func buildRateLimitHandler(host *models.ProxyHost, secCfg *models.SecurityConfig) (Handler, error) {
- // ... existing validation ...
+---
 
- h := Handler{"handler": "rate_limit"}
+## Testing Checklist
 
- // Build zone configuration
- zone := map[string]interface{}{
-  "key":        "{http.request.remote.host}",
-  "window":     fmt.Sprintf("%ds", secCfg.RateLimitWindowSec),
-  "max_events": secCfg.RateLimitRequests,
- }
+Before merging the fix:

+fix: upgrade Go to 1.25 for Caddy 2.10.2 compatibility
 
-**Summary:** This section contains a complete test plan to validate rate limiting configuration generation and runtime enforcement in Charon. Tests are grouped into Unit, Integration and E2E categories and prioritize quick unit coverage and high-impact integration tests.
+Caddy 2.10.2 requires Go 1.25 (declared in its go.mod). The previous
+commit incorrectly downgraded to Go 1.23 based on the false assumption
+that Go 1.25.5 doesn't exist.
 
-Goal: Verify the following behavior:
-- The `RateLimitBurst`, `RateLimitRequests`, `RateLimitWindowSec` and `RateLimitBypassList` fields are used by `buildRateLimitHandler` and emitted into the Caddy JSON configuration.
-- The Caddy `rate_limit` handler configuration uses `{http.request.remote.host}` as the key.
-- Bypass IPs are excluded from rate limiting by creating a subroute with `remote_ip` matcher.
-- At runtime, Caddy enforces limits, returns `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `Retry-After` headers (or documented equivalents), and resets counters after the configured window.
-- The plugin behaves correctly across multiple client IPs and respects bypass lists.
+This fix:
+- Updates Dockerfile Go images from 1.23-alpine to 1.25-alpine
+- Updates backend/go.mod to go 1.25
+- Updates go.work to go 1.25
 
------
-
-2.3.1 Files to Add / Edit
-- New scripts: `scripts/rate_limit_integration.sh` (shell integration test), `scripts/rate_limit_e2e.sh` (optional extended tests).
-- New integration test: `backend/integration/rate_limit_integration_test.go` (go test wrapper runs script).
-- Unit tests to add/edit: `backend/internal/caddy/config_test.go` (add `TestGenerateConfig_WithRateLimitBypassList` and `TestBuildRateLimitHandler_KeyIsRemoteHost`), `backend/internal/api/handlers/security_ratelimit_test.go` (validate API fields persist & UpdateConfig accepts rate_limit fields).
-
-2.3.2 Unit Tests (fast, run in CI pre-merge)
-- File: `backend/internal/caddy/config_test.go`
- - `TestGenerateConfig_WithRateLimitBypassList`
-  - Input: call `GenerateConfig` with `secCfg` set with `RateLimitEnable:true` and `RateLimitBypassList:"10.0.0.0/8,127.0.0.1/32"`; include one host.
-  - Assertions:
-   - The generated `Config` contains a route with `handler:"subroute"` or a `rate_limit` handler containing the bypass CIDRs (CIDRs found in JSON output).
-   - `RateLimitHandler` contains `rate_limits` map and `static` zone.
- - `TestBuildRateLimitHandler_KeyIsRemoteHost`
-  - Input: `secCfg` with valid values.
-  - Assertions: the static zone `key` is `{http.request.remote.host}`.
- - `TestBuildRateLimitHandler_DefaultBurstAndMax` (already present) and `TestParseBypassCIDRs` (existing) remain required.
-
-2.3.3 Integration Tests (CI gated, Docker required)
-We will add a scripted integration test to run inside CI or locally with Docker. The test will:
- - Start the `charon:local` image (build if not present) in a detached container named `charon-debug`.
- - Create a simple HTTP backend (httpbin/kennethreitz/httpbin) called `ratelimit-backend` (or `httpbin`).
- - Create a proxy host `ratelimit.local` pointing to the backend via the Charon API (use /api/v1/proxy-hosts).
- - Set `SecurityConfig` (POST /api/v1/security/config) with short windows for speed, e.g.:
-  ```json
-  {"name":"default","enabled":true,"rate_limit_enable":true,"rate_limit_requests":3,"rate_limit_window_sec":10,"rate_limit_burst":1}
-  ```
- - Validate that Caddy Admin API at `http://localhost:2019/config` includes a `rate_limit` handler and, where applicable, a `subroute` with bypass CIDRs (if `RateLimitBypassList` set).
- - Execute the runtime checks:
-  - Using a single client IP, send 3 requests in quick succession expecting HTTP 200.
-  - The 4th request (same client IP) should return HTTP 429 (Too Many Requests) and include a `Retry-After` header.
-  - On allowed responses, assert that `X-RateLimit-Limit` equals 3 and `X-RateLimit-Remaining` decrements.
-  - Wait until the configured `RateLimitWindowSec` elapses, and confirm requests are allowed again (headers reset).
-
- - Bypass List Validation:
-  - Set `RateLimitBypassList` to contain the requester's IP (or `127.0.0.1/32` when client runs from the host). Confirm repeated requests do not get `429`, and `X-RateLimit-*` headers may be absent or indicate non-enforcement.
-
- - Multi-IP Isolation:
-  - Spin up two client containers with different IPs (via Docker network `--subnet` + `--ip`). Each should have independent counters; both able to make configured number requests without affecting the other.
-
- - X-Forwarded-For behavior (Confirm remote.host is used as key):
-  - Send requests with `X-Forwarded-For` different than the container IP; observe rate counters still use the connection IP unless Caddy remote_ip plugin explicitly configured to respect XFF.
-
- - Test Example (Shell Snippet to assert headers)
-  ```bash
-  # Single request driver - check headers
-  curl -s -D - -o /dev/null -H "Host: ratelimit.local" http://localhost/post
-  # Expect headers: X-RateLimit-Limit: 3, X-RateLimit-Remaining: <number>
-  ```
-
- - Script name: `scripts/rate_limit_integration.sh` (mirrors style of `coraza_integration.sh`).
-
- - Manage flaky behavior:
-  - Retry a couple times and log Caddy admin API output on failure for debugging.
-+
-2.3.4 E2E Tests (Longer, optional)
-- Create `scripts/rate_limit_e2e.sh` which spins up the same environment but runs broader scenarios:
- - High-rate bursts (WindowSec small and Requests small) to test burst allowance/consumption.
- - Multi-minute stress run (not for every CI pass) to check long-term behavior and reset across windows.
- - SPA / browser test using Playwright / Cypress to validate UI controls (admin toggles rate limit presets and sets bypass list) and ensures that applied config is effective at runtime.
-
-2.3.5 Mock/Stub Guidance
-- IP Addresses
- - Use Docker network subnets and `docker run --network containers_default --ip 172.25.0.10` to guarantee client IP addresses for tests and to exercise bypass list behavior.
- - For tests run from host with `curl`, include `--interface` or `--local-port` if needed to force source IP (less reliable than container-based approach).
-- X-Forwarded-For
- - Add `-H "X-Forwarded-For: 10.0.0.5"` to `curl` requests; assert that plugin uses real connection IP by default. If future changes enable `real_ip` handling in Caddy, tests should be updated to reflect the new behavior.
-- Timing Windows
- - Keep small values (2-10 seconds) while maintaining reliability (1s windows are often flaky). For CI environment, `RateLimitWindowSec=10` with `RateLimitRequests=3` and `Burst=1` is a stable, fast choice.
-
-2.3.6 Test Data and Assertions (Explicit)
-- Unit Test: `TestBuildRateLimitHandler_ValidConfig`
- - Input: secCfg{Requests:100, WindowSec:60, Burst:25}
- - Assert: `h["handler"] == "rate_limit"`, `static".max_events == 100`, `burst == 25`.
-
-- Integration Test: `TestRateLimit_Enforcement_Basic`
- - Input: RateLimitRequests=3, RateLimitWindowSec=10, Burst=1, no bypass list
- - Actions: Send 4 rapid requests using client container
- - Expected outputs: [200, 200, 200, 429], 4th returns Retry-After or explicit block message
- - Assert: Allowed responses include `X-RateLimit-Limit: 3`, and `X-RateLimit-Remaining` decreasing
-
-- Integration Test: `TestRateLimit_BypassList_SkipsLimit`
- - Input: Same as above + `RateLimitBypassList` contains client IP CIDR
- - Expected outputs: All requests 200 (no 429)
-
-- Integration Test: `TestRateLimit_MultiClient_Isolation`
- - Input: As above
- - Actions: Client A sends 3 requests, Client B sends 3 requests
- - Expected: Both clients unaffected by the other; both get 200 responses for their first 3 requests
-
-- Integration Test: `TestRateLimit_Window_Reset`
- - Input: As above
- - Actions: Exhaust quota (get 429), wait `RateLimitWindowSec + 1`, issue a new request
- - Expected: New request is 200 again
-
-2.3.7 Test Harness - Example Go Integration Test
-Use the same approach as `backend/integration/coraza_integration_test.go`, run the script and check output for expected messages. Example test file: `backend/integration/rate_limit_integration_test.go`:
-
-```go
-//go:build integration
-// +build integration
-
-package integration
-
-import (
-  "context"
-  "os/exec"
-  "strings"
-  "testing"
-  "time"
-)
-
-func TestRateLimitIntegration(t *testing.T) {
-  t.Parallel()
-  ctx, cancel := context.WithTimeout(context.Background(), 10*time.Minute)
-  defer cancel()
-  cmd := exec.CommandContext(ctx, "bash", "./scripts/rate_limit_integration.sh")
-  out, err := cmd.CombinedOutput()
-  t.Logf("rate_limit_integration script output:\n%s", string(out))
-  if err != nil {
-    t.Fatalf("rate_limit integration failed: %v", err)
-  }
-  if !strings.Contains(string(out), "Rate limit enforcement succeeded") {
-    t.Fatalf("unexpected script output, rate limiting assertion not found")
-  }
-}
-```
-
-2.3.8 CI and Pre-commit Hooks
-
-- Add an integration CI job that runs the Docker-based script and the integration `go` test suite in a separate job to avoid blocking unit test runs on tools requiring Docker. Use a job matrix with `services: docker` and timeouts set appropriately.
-- Do not add integration scripts to pre-commit (too heavy); keep pre-commit focused on `go fmt`, `go vet`, `go test ./...` (unit tests), `npm test`, and lint rules.
-- Use the workspace `tasks.json` to add a `Coraza: Run Integration Script` style task for rate limit integration that mirrors `scripts/coraza_integration.sh`.
-
-2.3.9 .gitignore / .codecov.yml / Dockerfile changes
-
-- .gitignore
- 	- Add `test-results/rate_limit/` to avoid committing local script logs.
- 	- Add `scripts/rate_limit_integration.sh` output files (if any) to ignore.
-- .codecov.yml
- 	- Optional: If you want integration test coverage included, remove `**/integration/**` from `ignore` or add a specific `backend/integration/*_test.go` to be included. (Caveat: integration coverage may not be reproducible across CI).
-- .dockerignore
- 	- Ensure `scripts/` and `backend/integration` are not copied to reduce build context size if not needed in Docker build.
-- Dockerfile
- 	- Confirm presence of `--with github.com/mholt/caddy-ratelimit` in the xcaddy build (it is present in base Dockerfile). Add comment and assert plugin presence in integration script by checking `caddy version` or `caddy list` available modules.
-
-2.3.10 Prioritization
-
-- P0: Integration test `TestRateLimit_Enforcement_Basic` (high confidence: verifies actual runtime limit enforcement and header presence)
-- P1: Unit tests verifying config building (`TestGenerateConfig_WithRateLimitBypassList`, `TestBuildRateLimitHandler_KeyIsRemoteHost`) and API tests for `POST /security/config` handling rate limit fields
-- P2: Integration tests for bypass list, multi-client isolation, window reset
-- P3: E2E tests for UI configuration of rate limiting and long-running stress tests
-
-2.3.11 Next Steps
-
-- Implement `scripts/rate_limit_integration.sh` and `backend/integration/rate_limit_integration_test.go` following `coraza_integration.sh` as the blueprint.
-- Add unit tests to `backend/internal/caddy/config_test.go` and API handler tests in `backend/internal/api/handlers/security_ratelimit_test.go`.
-- Add Docker network helpers and ensure `docker run --ip` is used to control client IPs during integration.
-- Run all new tests locally (Docker required) and in CI. Add integration job to GitHub Actions with `runs-on: ubuntu-latest`, `services: docker` and appropriate timeouts.
-
------
-
-This test plan should serve as a complete specification for testing rate limiting behavior across unit, integration, and E2E tiers. The next iteration will include scripted test implementations and Jenkins/GHA job snippets for CI.

-### Phase 3: CrowdSec Bouncer (Issue #17)
+## Files to Modify (Summary)
 
-**Goal:** Implement actual IP reputation checking against CrowdSec decisions.
-
-#### 3.1 Current State Analysis
-
-- CrowdSec binary installed in Docker image
-- `caddy-crowdsec-bouncer` plugin compiled into Caddy
-- `buildCrowdSecHandler` returns a handler but only sets `api_url`
-- Comment in `cerberus.go`: "CrowdSec placeholder: integration would check CrowdSec API"
-- No actual decision lookup code
-
-#### 3.2 Architecture Decision
-
-**Two approaches:**
-
-| Approach | Pros | Cons |
-|----------|------|------|
-| **A: Caddy Plugin** | Offloads to Caddy, less Go code | Requires Caddy config regeneration |
-| **B: Middleware** | Real-time, Go-native | Duplicates bouncer logic |
-
-**Recommendation:** Use **Approach A** (Caddy Plugin) since `caddy-crowdsec-bouncer` is already compiled in. Enhance the handler configuration.
-
-#### 3.3 Required Changes
-
-##### 3.3.1 Update CrowdSec Handler Builder
-
-**File:** `backend/internal/caddy/config.go`
-
-```go
-// buildCrowdSecHandler returns a CrowdSec bouncer handler.
-// See: https://github.com/hslatman/caddy-crowdsec-bouncer
-func buildCrowdSecHandler(host *models.ProxyHost, secCfg *models.SecurityConfig, crowdsecEnabled bool) (Handler, error) {
- if !crowdsecEnabled {
-  return nil, nil
- }
-
- h := Handler{"handler": "crowdsec"}
-
- // API URL (required)
- apiURL := "http://localhost:8080"
- if secCfg != nil && secCfg.CrowdSecAPIURL != "" {
-  apiURL = secCfg.CrowdSecAPIURL
- }
- h["api_url"] = apiURL
-
- // API Key (from environment or config)
- apiKey := os.Getenv("CROWDSEC_API_KEY")
- if apiKey == "" && secCfg != nil {
-  // Could store encrypted in DB - for now use env var
- }
- if apiKey != "" {
-  h["api_key"] = apiKey
- }
-
- // Ticker interval for decision sync (default 30s)
- h["ticker_interval"] = "30s"
-
- // Enable streaming mode for real-time updates
- h["enable_streaming"] = true
-
- return h, nil
-}
-```
-
-##### 3.3.2 Add CrowdSec Registration on Startup
-
-**File:** `backend/internal/crowdsec/registration.go` (new)
-
-```go
-// Package crowdsec handles CrowdSec LAPI integration.
-package crowdsec
-
-import (
- "bytes"
- "encoding/json"
- "fmt"
- "net/http"
- "os"
- "os/exec"
- "time"
-)
-
-// EnsureBouncerRegistered registers the Caddy bouncer with local CrowdSec LAPI.
-func EnsureBouncerRegistered(lapiURL string) (string, error) {
- // Check if already registered
- apiKey := os.Getenv("CROWDSEC_API_KEY")
- if apiKey != "" {
-  return apiKey, nil
- }
-
- // Use cscli to register bouncer
- cmd := exec.Command("cscli", "bouncers", "add", "caddy-bouncer", "-o", "raw")
- output, err := cmd.Output()
- if err != nil {
-  // May already exist, try to get existing key
-  return "", fmt.Errorf("failed to register bouncer: %w", err)
- }
-
- apiKey = string(bytes.TrimSpace(output))
- return apiKey, nil
-}
-
-// CheckLAPIHealth verifies CrowdSec LAPI is responding.
-func CheckLAPIHealth(lapiURL string) bool {
- client := &http.Client{Timeout: 5 * time.Second}
- resp, err := client.Get(lapiURL + "/v1/decisions")
- if err != nil {
-  return false
- }
- defer resp.Body.Close()
- // 401 is expected without auth, but means LAPI is up
- return resp.StatusCode == 401 || resp.StatusCode == 200
-}
-```
-
-##### 3.3.3 Update Cerberus Middleware (Optional - for logging)
-
-**File:** `backend/internal/cerberus/cerberus.go`
-
-The actual blocking is handled by the Caddy CrowdSec bouncer plugin. However, we can add logging in Cerberus:
-
-```go
-// In Middleware(), after ACL check:
-// CrowdSec logging (actual blocking is done by Caddy bouncer)
-if c.cfg.CrowdSecMode == "local" {
- // Log that CrowdSec is active (blocking happens at Caddy layer)
- logger.Log().WithField("client_ip", ctx.ClientIP()).Debug("Request evaluated by CrowdSec bouncer")
-}
-```
-
-##### 3.3.4 Add CrowdSec Status Endpoint Enhancement
-
-**File:** `backend/internal/api/handlers/crowdsec_handler.go`
-
-```go
-// GetCrowdSecDecisions returns recent decisions from CrowdSec LAPI
-func (h *CrowdSecHandler) GetDecisions(c *gin.Context) {
- lapiURL := os.Getenv("CROWDSEC_LAPI_URL")
- if lapiURL == "" {
-  lapiURL = "http://localhost:8080"
- }
-
- apiKey := os.Getenv("CROWDSEC_API_KEY")
- if apiKey == "" {
-  c.JSON(http.StatusServiceUnavailable, gin.H{"error": "CrowdSec API key not configured"})
-  return
- }
-
- client := &http.Client{Timeout: 10 * time.Second}
- req, _ := http.NewRequest("GET", lapiURL+"/v1/decisions", nil)
- req.Header.Set("X-Api-Key", apiKey)
-
- resp, err := client.Do(req)
- if err != nil {
-  c.JSON(http.StatusBadGateway, gin.H{"error": "Failed to connect to CrowdSec LAPI"})
-  return
- }
- defer resp.Body.Close()
-
- var decisions []map[string]interface{}
- json.NewDecoder(resp.Body).Decode(&decisions)
- c.JSON(http.StatusOK, gin.H{"decisions": decisions})
-}
-```
-
-#### 3.4 Frontend Updates
-
-**File:** `frontend/src/pages/CrowdSecConfig.tsx`
-
-Add decisions viewer panel:
-
-```tsx
-// In CrowdSecConfig component:
-const { data: decisions } = useQuery({
-  queryKey: ['crowdsec-decisions'],
-  queryFn: () => client.get('/api/v1/crowdsec/decisions').then(r => r.data),
-  enabled: status?.crowdsec?.enabled,
-  refetchInterval: 30000,
-})
-
-// Render decisions table
-{decisions?.decisions?.length > 0 && (
-  <Card>
-    <h3>Active Decisions</h3>
-    <table>
-      <thead>

-        </tr>
-      </thead>
-      <tbody>
-        {decisions.decisions.map((d: Decision) => (
-          <tr key={d.id}>
-            <td>{d.value}</td>
-            <td>{d.type}</td>
-            <td>{d.scenario}</td>
-            <td>{formatExpiry(d.until)}</td>
-          </tr>

-### Phase 4: WAF Integration (Issue #18) - Most Complex
+## Related Issues
 
-**Goal:** Generate actual Coraza configuration, per-host toggle, rule exclusions, paranoia levels.
+- Previous (incorrect) fix commit: `481208c` "fix: correct Go version to 1.23 in Dockerfile (1.25.5 does not exist)"
+- Previous commit: `65443a1` "fix: correct Go version to 1.23 (1.25.5 does not exist)"
 
-#### 4.1 Current State Analysis
-
-- `cerberus.go` only checks for literal `<script>` string in URL (trivial bypass)
-- `buildWAFHandler` in `config.go` creates Coraza handler but requires ruleset
-- Frontend (`WafConfig.tsx`) manages rule sets but no per-host toggle
-- No paranoia level selector
-- No rule exclusion system for false positives

-##### 4.2.2 Add Per-Host WAF Toggle
-
-**File:** `backend/internal/models/proxy_host.go`
-
-```go
-type ProxyHost struct {
- // ... existing fields ...
- WAFDisabled bool `json:"waf_disabled" gorm:"default:false"` // Override global WAF
-}
-```
-
-##### 4.2.3 Add Paranoia Level and Exclusions to SecurityConfig
-
-**File:** `backend/internal/models/security_config.go`
-
-```go
-type SecurityConfig struct {
- // ... existing fields ...
- WAFParanoiaLevel int    `json:"waf_paranoia_level" gorm:"default:1"` // 1-4
- WAFExclusions    string `json:"waf_exclusions" gorm:"type:text"`     // JSON array of exclusions
-}
-```
-
-##### 4.2.4 Remove Naive Check from Cerberus Middleware
-
-**File:** `backend/internal/cerberus/cerberus.go`
-
-The current `<script>` check is misleading. Replace with proper logging:
-
-```go
-// WAF is handled by Coraza at the Caddy layer
-// Log WAF status for debugging
-if c.cfg.WAFMode != "" && c.cfg.WAFMode != "disabled" {
- logger.Log().WithFields(map[string]interface{}{
-  "source":    "waf",
-  "mode":      c.cfg.WAFMode,
-  "client_ip": ctx.ClientIP(),
- }).Debug("Request subject to WAF inspection")
-}
-```
-
-##### 4.2.5 Add Rule Exclusion Management Endpoints
-
-**File:** `backend/internal/api/handlers/security_handler.go`
-
-```go
-// GetWAFExclusions returns current WAF rule exclusions
-func (h *SecurityHandler) GetWAFExclusions(c *gin.Context) {
- cfg, err := h.svc.Get()
- if err != nil && err != services.ErrSecurityConfigNotFound {
-  c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to get config"})
-  return
- }
-
- var exclusions []WAFExclusion
- if cfg != nil && cfg.WAFExclusions != "" {
-  json.Unmarshal([]byte(cfg.WAFExclusions), &exclusions)
- }
- c.JSON(http.StatusOK, gin.H{"exclusions": exclusions})
-}
-
-// AddWAFExclusion adds a rule exclusion
-func (h *SecurityHandler) AddWAFExclusion(c *gin.Context) {
- var exclusion WAFExclusion
- if err := c.ShouldBindJSON(&exclusion); err != nil {
-  c.JSON(http.StatusBadRequest, gin.H{"error": "Invalid payload"})
-  return
- }
-
- cfg, _ := h.svc.Get()
- if cfg == nil {
-  cfg = &models.SecurityConfig{Name: "default"}
- }
-
- var exclusions []WAFExclusion
- if cfg.WAFExclusions != "" {
-  json.Unmarshal([]byte(cfg.WAFExclusions), &exclusions)
- }
-
- exclusions = append(exclusions, exclusion)
- data, _ := json.Marshal(exclusions)

-
- if err := h.svc.Upsert(cfg); err != nil {
-  c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to save"})
-  return
- }
-
- // Apply to Caddy
- if h.caddyManager != nil {
-  h.caddyManager.ApplyConfig(c.Request.Context())
- }
-
- c.JSON(http.StatusOK, gin.H{"exclusion": exclusion})
-}
-```
-
-**Routes:**
-
-- `GET /api/v1/security/waf/exclusions`
-- `POST /api/v1/security/waf/exclusions`
-- `DELETE /api/v1/security/waf/exclusions/:id`
-
-#### 4.3 Frontend Updates
-
-##### 4.3.1 Update WafConfig Page
-
-**File:** `frontend/src/pages/WafConfig.tsx`
-
-Add:
-
-1. Paranoia level selector (1-4 with descriptions)
-2. Exclusions management panel
-3. Per-host override indicator
-
-```tsx
-// Paranoia level selector
-const PARANOIA_LEVELS = [
-  { level: 1, name: 'Low', description: 'Minimal false positives, basic protection' },
-  { level: 2, name: 'Medium', description: 'Balanced protection, some false positives' },
-  { level: 3, name: 'High', description: 'Strong protection, requires tuning' },
-  { level: 4, name: 'Paranoid', description: 'Maximum protection, many false positives' },
-]
-
-// In render:
-<div>
-  <label>Paranoia Level</label>
-  <select value={paranoiaLevel} onChange={...}>
-    {PARANOIA_LEVELS.map(p => (
-      <option key={p.level} value={p.level}>
-        {p.level} - {p.name}
-      </option>
-    ))}
-  </select>
-  <p className="text-xs text-gray-500">
-    {PARANOIA_LEVELS.find(p => p.level === paranoiaLevel)?.description}
-  </p>
-</div>
-```
-
-##### 4.3.2 Add Per-Host WAF Toggle to Proxy Host Form
-
-**File:** `frontend/src/pages/ProxyHostForm.tsx` (or similar)
-
-```tsx
-<Switch
-  label="Disable WAF for this host"
-  checked={formData.waf_disabled}
-  onChange={(e) => setFormData({...formData, waf_disabled: e.target.checked})}
-  helperText="Override global WAF settings for this specific host"
-/>
-```
-
-#### 4.4 Test Requirements
-
-**File:** `backend/internal/caddy/config_waf_test.go`
-
-```go
-func TestBuildWAFHandler_ParanoiaLevel(t *testing.T) {
- secCfg := &models.SecurityConfig{
-  WAFMode:          "block",
-  WAFParanoiaLevel: 2,
- }
- h, err := buildWAFHandler(nil, nil, nil, secCfg, true)
- require.NoError(t, err)
- directives := h["directives"].(string)
- assert.Contains(t, directives, "tx.paranoia_level=2")
-}
-
-func TestBuildWAFHandler_Exclusions(t *testing.T) {
- exclusions := []WAFExclusion{
-  {RuleID: 942100, Description: "SQL injection false positive"},
- }
- data, _ := json.Marshal(exclusions)
- secCfg := &models.SecurityConfig{
-  WAFMode:       "block",
-  WAFExclusions: string(data),
- }
- h, err := buildWAFHandler(nil, nil, nil, secCfg, true)
- require.NoError(t, err)
- directives := h["directives"].(string)
- assert.Contains(t, directives, "SecRuleRemoveById 942100")
-}
-
-func TestBuildWAFHandler_PerHostDisabled(t *testing.T) {
- host := &models.ProxyHost{WAFDisabled: true}
- secCfg := &models.SecurityConfig{WAFMode: "block"}
- h, err := buildWAFHandler(host, nil, nil, secCfg, true)
- require.NoError(t, err)
- assert.Nil(t, h)
-}
-```
+Both commits should be effectively reverted by this fix.

-## Implementation Order
-
-1. **Phase 2 (Rate Limit)** - Quickest, enables immediate value
-2. **Phase 1 (GeoIP)** - Most user-requested feature
-3. **Phase 4 (WAF)** - Most complex but highest security impact
-4. **Phase 3 (CrowdSec)** - Requires external service coordination
+Source: <https://go.dev/dl/?mode=json>

-   - **Severity:** Low (test sync issue)
-   - **Fix:** Updated assertion to expect `'Coraza'`
-
-2. **Security.test.tsx - Lines 252-267 (WAF Controls describe block)**

-## Changes Made During QA
-
-### Test File Update: Security.test.tsx
-
-```diff
-- describe('WAF Controls', () => {
--   it('should change WAF mode', async () => { ... })
--   it('should change WAF ruleset', async () => { ... })
-- })
-+ // Note: WAF Controls tests removed - dropdowns moved to dedicated WAF config page (/security/waf)
-
-- expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'WAF (Coraza)', 'Rate Limiting', 'Live Security Logs'])
-+ expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'Coraza', 'Rate Limiting', 'Live Security Logs'])
+```text
+No vulnerabilities found.
 ```
 
+The project has no known security vulnerabilities in Go dependencies.
+

+
+## Go Version Configuration Status
+
+The current Go version configuration is:
+
+| File | Go Version | Status |
+|------|------------|--------|
+| Dockerfile | 1.23 | ✅ Correct |
+| backend/go.mod | 1.23 | ✅ Correct |
+| go.work | 1.23 | ✅ Correct |
+
+**Note:** The Renovate configuration was previously attempting to update to Go 1.25.5, which does not exist. The configuration has been corrected.
+

 ## Recommendations
 
-1. **No blocking issues** - All changes are complete and verified.
+### Immediate Actions
 
-2. **Pre-existing warnings** - Consider addressing the `@typescript-eslint/no-explicit-any` warnings in `CrowdSecConfig.tsx` and its test file in a future cleanup pass.
+1. **Create missing test fixture:**
+
+   ```bash
+   # Create backend/internal/crowdsec/testdata/hub_index.json
+   # with appropriate test data for hub index
+   ```
+
+2. **Review flaky test:**
+   - Investigate `TestApplyRepullsOnCacheExpired` for race conditions
+   - Add appropriate synchronization or increase timeouts if needed
+
+### Optional Improvements
+
+1. **Fix frontend lint warnings:**
+   - Remove unused `onclick` variable in security-mobile.spec.ts
+   - Add missing dependencies to useEffect or use `// eslint-disable-next-line`
+   - Replace `any` types with proper TypeScript types
+
+2. **Sync version file:**
+   - Update `.version` to match latest tag if appropriate

-| `scripts/rate_limit_integration.sh` | ✅ PASS |
-| `backend/integration/rate_limit_integration_test.go` | ✅ PASS |
-| `.vscode/tasks.json` | ✅ PASS |
-
-### Validation Results
-
-#### 1. Shell Script: `rate_limit_integration.sh`
-
-**Syntax Check**: `bash -n scripts/rate_limit_integration.sh`
-
-- **Result**: ✅ No syntax errors detected
-
-**ShellCheck Static Analysis**: `shellcheck --severity=warning`
-
-- **Result**: ✅ No warnings or errors
-
-**File Permissions**:
-
-- **Result**: ✅ Executable (`-rwxr-xr-x`)
-- **File Type**: Bourne-Again shell script, UTF-8 text
-
-**Security Review**:
-
-- ✅ Uses `set -euo pipefail` for strict error handling
-- ✅ Uses `$(...)` for command substitution (not backticks)
-- ✅ Proper quoting around variables
-- ✅ Cleanup trap function properly defined
-- ✅ Error handler (`on_failure`) captures debug info
-- ✅ Temporary files cleaned up in cleanup function
-- ✅ No hardcoded secrets or credentials
-- ✅ Uses `mktemp` for temporary cookie file
-
-#### 2. Go Integration Test: `rate_limit_integration_test.go`
-
-**Build Verification**: `go build -tags=integration ./integration/...`
-
-- **Result**: ✅ Compiles successfully
-
-**Code Review**:
-
-- ✅ Proper build tag: `//go:build integration`
-- ✅ Backward-compatible build tag: `// +build integration`
-- ✅ Uses `t.Parallel()` for concurrent test execution
-- ✅ Context timeout of 10 minutes (appropriate for rate limit window tests)
-- ✅ Captures combined output for debugging
-- ✅ Validates key assertions in script output
-
-#### 3. VS Code Tasks: `tasks.json`
-
-**JSON Validation**: Strip JSONC comments, parse as JSON
-
-- **Result**: ✅ Valid JSON structure
-
-**New Tasks Verified**:
-
-| Task Label | Command | Status |
-|------------|---------|--------|
-| `Rate Limit: Run Integration Script` | `bash ./scripts/rate_limit_integration.sh` | ✅ Valid |
-| `Rate Limit: Run Integration Go Test` | `go test -tags=integration ./integration -run TestRateLimitIntegration -v` | ✅ Valid |
-
-### Issues Found
-
-**None** - All files pass syntax validation and security review.
-
-### Recommendations
-
-1. **Documentation**: Consider adding inline comments to the Go test explaining the expected test flow for future maintainers.
-
-2. **Timeout Tuning**: The 10-minute timeout in the Go test is generous. If tests consistently complete faster, consider reducing to 5 minutes.
-
-3. **CI Integration**: Ensure the integration tests are properly gated in CI/CD pipelines to avoid running on every commit (Docker dependency).
-
-### Rate Limiter Infrastructure Summary
-
-The rate limiter test infrastructure has been verified and is **ready for use**. All three files pass syntax validation, compile/parse correctly, and follow security best practices.
-
-**Overall Status**: ✅ **APPROVED**
