Security Review — frontend/src/pages/Uptime.tsx

Finding 1: XSS Risk — <p>{urlError}</p>

Assessment: ✅ NOT EXPLOITABLE

urlError is set exclusively by the component itself:

setUrlError(t('uptime.invalidTcpFormat'));  // from i18n translation
setUrlError('');                             // clear

The value always originates from the i18n translation system, never from raw user input. React JSX rendering ({urlError}) performs automatic HTML entity escaping on all string values. Even if a translation file were compromised to contain HTML tags, React would render them as escaped text. No XSS vector exists.

---

Finding 2: url.includes('://') Bypass Risk

Assessment: ⚠️ LOW — UX guard only; backend must be authoritative

The scheme check url.trim().includes('://') correctly intercepts the primary misuse pattern (tcp://, http://, ftp://, etc.). Edge cases:

• Percent-encoded bypass: tcp%3A//host:8080 does not contain the literal :// and would pass the frontend guard, reaching the backend with the raw percent-encoded value.
• data: URIs: Use : not :// — would pass the frontend check but would fail at the backend as an invalid TCP target.
• Internal whitespace: tcp ://host is not caught (.trim() strips only leading/trailing whitespace).

All bypass paths result in an invalid monitor that fails to connect. There is no SSRF risk, credential leak, or XSS vector from these edge cases. The backend API is the authoritative validator.

Recommendation: No frontend change required. Confirm the backend validates TCP monitor URLs server-side (host:port format) independent of client input.

---

Finding 3: handleSubmit Guard — Path Analysis

Assessment: ✅ DEFENSE-IN-DEPTH OPERATING AS DESIGNED

Three independent submission guards are present:

1. HTML required attribute on name and url inputs — browser-enforced
2. Button disabled state: disabled={mutation.isPending || !name.trim() || !url.trim()}
3. JS guard in handleSubmit: early return on empty fields, followed by TCP scheme check

All three must be bypassed for an invalid TCP URL to reach the API through normal UI interaction. Direct API calls bypass all three layers by design; backend validation covers that path. The guard fires correctly in all 10 test-covered scenarios.

---

Finding 4: <a href={monitor.url}> with TCP Addresses (Informational)

Assessment: ℹ️ INFORMATIONAL — No security risk

TCP monitor URLs (e.g., 192.168.1.1:8080) are rendered inside <a href={monitor.url}>. A browser interprets this as a relative URL reference; clicking it fails gracefully. React sanitizes javascript: hrefs since v16.9.0. No security impact.

---

Summary

Check	Result	Notes
TypeScript	✅ PASS	0 errors
ESLint	✅ PASS	0 errors, 839 pre-existing warnings
Local Patch Report	✅ PASS	Artifacts generated
Unit Tests (TCP UX)	✅ PASS	10/10
Full Unit Suite	✅ NO FAILURES OBSERVED	Coverage % deferred to CI
Lefthook Pre-commit	✅ PASS	All 6 active hooks passed
Trivy	⚠️ N/A	Not installed; Semgrep used as compensating control
Semgrep	✅ PASS	0 findings
XSS (urlError)	✅ NOT EXPLOITABLE	i18n value + React JSX escaping
Scheme check bypass	⚠️ LOW	Frontend UX guard only; backend must validate
handleSubmit guard	✅ CORRECT	Defense-in-depth as designed

---

Overall: ✅ PASS

PR-5 implements TCP monitor UX with correct validation layering, clean TypeScript, and complete unit test coverage of all TCP-specific behaviors. One low-severity observation (backend must own TCP URL format validation independently) does not block the PR — this is an existing project convention, not a regression introduced by these changes.

QA Security Audit Report — Rate Limit CI Fix

Audited by: QA Security Auditor Date: 2026-03-17 Spec reference: docs/plans/rate_limit_ci_fix_spec.md Files audited:

• scripts/rate_limit_integration.sh
• Dockerfile (GeoIP section, non-CI path)
• .github/workflows/rate-limit-integration.yml

Caddy admin API trailing slash (script)	All 6 occurrences of localhost:2119/config in script	✅ PASS — all use /config/

---

Security Focus Area Results

1. Credential Handling — TMP_COOKIE

mktemp usage: TMP_COOKIE=$(mktemp) at line 208. Creates a file in /tmp with 600 permissions via the OS. ✅ SECURE.

Removal on exit: The cleanup() function at line 103 removes the file with rm -f "${TMP_COOKIE:-}". However, cleanup is only registered via explicit calls — there is no trap cleanup EXIT. Only trap on_failure ERR is registered (line 108).

Gap: On 5 early exit 1 paths after line 208 (login failure L220, auth failure L251, Caddy readiness failure L282, security config failure L299, and handler verification failure L316), cleanup is never called. The cookie file is left in /tmp.

Severity: LOW — The cookie contains session credentials for a localhost test server (ratelimit@example.local / password123, non-production). CI runners are ephemeral and auto-cleaned. Local runs will leave a /tmp/tmp.XXXXXX file until next reboot or manual cleanup.

Note: The exit at line 386 (inside the 429 enforcement failure block) intentionally skips cleanup to leave containers running for manual inspection. This is by design and acceptable.

Recommendation: Add trap cleanup EXIT immediately after trap on_failure ERR (line 109) to ensure the cookie file is always removed.

---

2. curl — Sensitive Values in Command-Line Arguments

Cookie file path is passed via -c ${TMP_COOKIE} and -b ${TMP_COOKIE} (unquoted). No credentials, tokens, or API keys are passed as command-line arguments. All authentication is via the cookie file (read/write by path), which is the correct pattern — cookie values never appear in ps output.

Finding (LOW): ${TMP_COOKIE} is unquoted in all 6 curl invocations. mktemp on Linux produces paths of the form /tmp/tmp.XXXXXX which never contain spaces or shell metacharacters under default $TMPDIR. However, under a non-standard $TMPDIR (e.g., /tmp/my dir/) this would break. This is a portability issue, not a security issue.

Recommendation: Quote "${TMP_COOKIE}" in all curl invocations.

---

3. Shell Injection

All interpolated values in curl -d payloads are either:

• Script-level constants (RATE_LIMIT_REQUESTS=3, RATE_LIMIT_WINDOW_SEC=10, RATE_LIMIT_BURST=1, TEST_DOMAIN=ratelimit.local, BACKEND_CONTAINER=ratelimit-backend)
• Values derived from API responses stored in double-quoted variables ("$CREATE_RESP", "$SEC_CONFIG_RESP")

No shell injection vector exists. All heredoc expansions (cat <<EOF...EOF) expand only the hardcoded constants listed above.

The UUID extraction pattern at line 429 includes ${TEST_DOMAIN} unquoted within a grep -o pattern, but because the variable expands to ratelimit.local (controlled constant), this has no injection risk. The . in ratelimit.local is treated as a regex wildcard but in this context only matches the intended hostname. ✅ PASS.

---

4. set -euo pipefail Compatibility

The new status-capture idiom:

LOGIN_STATUS=$(curl -s -w "\n%{http_code}" ... | tail -n1)

Behavior under set -euo pipefail:

• Network failure (curl exits non-zero, e.g., ECONNREFUSED): pipefail propagates curl's non-zero exit through the pipeline; the assignment fails; set -e fires the on_failure ERR trap and exits. ✅ Correct.
• HTTP error (curl exits 0, HTTP 4xx/5xx): curl outputs \n{code}; tail -n1 extracts the code; assignment succeeds; subsequent [ "$LOGIN_STATUS" != "200" ] detects the failure. ✅ Correct.
• Empty body edge case: If curl returns an empty body, output is \n200. tail -n1 → 200; head -n-1 → empty string. Status check still works. ✅ Correct.

The SEC_CONFIG_RESP split pattern (tail -n1 for status, head -n-1 for body) is correct for both single-line and multiline JSON responses. ✅ PASS.

---

5. Workflow Secrets Exposure

The workflow (rate-limit-integration.yml) contains no ${{ secrets.* }} references. All test credentials are hardcoded constants in the script (ratelimit@example.local / password123), appropriate for an ephemeral test user that is registered and used only within the test run.

$GITHUB_STEP_SUMMARY output includes: container status, API config JSON, container logs. None of these contain secrets or credentials. The security config JSON may contain rate limit settings (integers) but nothing sensitive.

No accidental log exposure identified. ✅ PASS.

---

6. GeoIP Change — Supply-Chain Risk

Change: The non-CI Dockerfile build path previously ran sha256sum -c - against GEOLITE2_COUNTRY_SHA256. This was removed. The remaining guard is [ -s /app/data/geoip/GeoLite2-Country.mmdb ] (file-size non-empty check).

Risk assessment (MEDIUM): The download source is https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb, a public GitHub repository. If this repository is compromised or the file is replaced with a malicious binary:

• The -s check only verifies the file is non-empty
• The application loads it at CHARON_GEOIP_DB_PATH for IP geolocation — a non-privileged read operation
• A malicious file would not achieve RCE via MMDb parsing in the MaxMind reader library (no known attack surface), but could corrupt GeoIP lookups silently

This is an acknowledged, pre-existing architectural limitation documented in the spec. The sha256sum check was ineffective by design because the P3TERX repository updates the file continuously while the pinned hash only updates weekly via update-geolite2.yml. The new behavior (accept any non-empty file) is more honest about the actual constraint.

Spec compliance: ARG GEOLITE2_COUNTRY_SHA256 is retained in the Dockerfile (line ~441) as required by the spec, preserving update-geolite2.yml workflow compatibility. ✅ PASS.

Residual risk: MEDIUM. Mitigated by: (1) wget uses HTTPS to fetch from GitHub (TLS in transit), (2) downstream Trivy scans of the built image would flag a malicious MMDB independently, (3) the GeoIP reader is sandboxed to a read operation with no known parse-exploit surface.

Correctness Against Spec

Spec Change	Implemented	Verified
C1: Login status check (Step 4)	✅ Yes — LOGIN_STATUS checked, fails fast on non-200	Script lines 211–220
C2: Proxy host creation — auth failures fatal, 409 continues	✅ Yes — 401/403 abort, other non-201 continues	Script lines 248–256
C3: Caddy admin API readiness gate before security config POST	✅ Yes — 20-retry loop before SEC_CFG call	Script lines 274–284
C4: Security config POST status checked	✅ Yes — SEC_CONFIG_STATUS checked, body logged on error	Script lines 286–301
C5: verify_rate_limit_config failure is hard exit	✅ Yes — prints debug and exit 1	Script lines 307–318
C6: Pre-verification sleep increased 5 → 8 s	✅ Yes — sleep 8	Script line 305
C7: Trailing slash on /config/	✅ Yes — all 6 script occurrences; workflow line 71	Confirmed by grep
Dockerfile: sha256sum removed from non-CI path	✅ Yes — only -s check remains	Dockerfile lines ~453–463
Dockerfile: ARG GEOLITE2_COUNTRY_SHA256 retained	✅ Yes — line ~441	Dockerfile audited
Workflow: debug dump uses /config/	✅ Yes — line 71	Confirmed by grep

---

Findings Summary

ID	Severity	Area	Description
M1	MEDIUM	Dockerfile supply-chain	GeoIP downloaded without hash; -s is minimum viability only. Accepted trade-off per spec — hash was perpetually stale.
L1	LOW	Shell security	${TMP_COOKIE} unquoted in 6 curl invocations. No practical impact under standard $TMPDIR.
L2	LOW	Temp file hygiene	No trap cleanup EXIT; TMP_COOKIE and containers not cleaned on 5 early failure paths (lines 220, 251, 282, 299, 316). Low sensitivity (localhost test credentials only).

No CRITICAL or HIGH severity findings.

---

Overall Verdict

✅ APPROVED

All spec-required changes are correctly implemented. No OWASP Top 10 vulnerabilities were introduced. The two LOW findings (unquoted variable, missing EXIT trap) are hygiene improvements that do not block the fix. The MEDIUM GeoIP supply-chain concern is a pre-existing architectural trade-off explicitly acknowledged in the spec.

Recommended follow-up (non-blocking)

Add trap cleanup EXIT immediately after trap on_failure ERR in scripts/rate_limit_integration.sh to ensure TMP_COOKIE is always removed and containers are cleaned on all exit paths. Purpose: Allow admins to set a setting to an empty string value (required to fix the fresh-install CrowdSec enabling bug where value was legitimately empty).

---

Overall Verdict: APPROVED

All structural, linting, and security gates pass. The change is correctly scoped to the build-only frontend-builder stage and introduces no new attack surface in the final runtime image.

No errors or warnings in the frontend-builder section.

---

3. Logical Security Review

Attack surface — build-only stage

The frontend-builder stage is strictly a build artifact producer. The final runtime image receives only compiled frontend assets via a single targeted COPY:

COPY --from=frontend-builder /app/frontend/dist /app/frontend/dist

The Alpine OS packages upgraded by apk upgrade --no-cache, the globally installed npm binary, and all node_modules are confined to the builder layer and never reach the runtime image. The CVE remediation has zero footprint in the deployed container.

--no-audit flag

--no-audit suppresses npm audit output during npm install -g npm@${NPM_VERSION}. This applies only to the single-package global npm tool upgrade, not to the project dependency installation. npm ci on line 111 installs project dependencies from package-lock.json and is unaffected by this flag. Suppressing audit during a build-time tool upgrade is the standard pattern for avoiding advisory database noise that cannot be acted on during the image build.

npm cache clean --force

Clears the npm package cache between the global npm upgrade and the npm ci run. This is safe: it ensures the freshly installed npm binary is used without stale cache entries left by the older npm version bundled in the base image. The --force flag suppresses npm's deprecation warning about manual cache cleaning; it does not alter the clean operation itself.

Blocking Issues

None.

Supply Chain Security Scan Report — CVE Investigation

Date: 2026-03-19 Scope: Charon project at /projects/Charon Tools: Grype 0.109.1, Syft 1.42.2 Go Toolchain: go1.26.1

---

Executive Summary

The CVEs flagged for goxmldsig, buger/jsonparser, and jackc/pgproto3/v2 are false positives for the Charon project. These packages are not in Charon's Go module dependency graph. They originate from Go build info embedded in third-party compiled binaries shipped inside the Docker image — specifically the CrowdSec and Caddy binaries.

CVE-2026-33186 (google.golang.org/grpc) is resolved in Charon's own source code (bumped to v1.79.3), but the same CVE still appears in the SBOM because older grpc versions are embedded in the CrowdSec (v1.74.2) and Caddy (v1.79.1) binaries in the Docker image. Those are out-of-scope for Charon to patch directly.

The most actionable findings are stale compiled Charon binaries built with go1.25.4–go1.25.6 that carry Critical/High stdlib CVEs and should be rebuilt with the current go1.26.1 toolchain.

---

1. Root Cause: Why These Packages Appear in Scans

Mechanism: go-module-binary-cataloger

When Syft generates the SBOM from the Docker image (not from source), it uses the go-module-binary-cataloger to read embedded Go build info from all compiled Go binaries in the image. Every Go binary compiled since Go 1.18 embeds a complete list of its upstream module dependencies via debug/buildinfo.

This means Syft finds packages from any Go binary on the image filesystem — including third-party tools like CrowdSec and Caddy — and reports them as if they were Charon dependencies.

Confirmed Binary Sources

Package	Version	Binary Path	Binary's Main Module
github.com/buger/jsonparser	v1.1.1	/usr/local/bin/crowdsec, /usr/local/bin/cscli	github.com/crowdsecurity/crowdsec
github.com/jackc/pgproto3/v2	v2.3.3	/usr/local/bin/crowdsec, /usr/local/bin/cscli	github.com/crowdsecurity/crowdsec
github.com/russellhaering/goxmldsig	v1.5.0	/usr/bin/caddy	caddy
google.golang.org/grpc	v1.74.2	/usr/local/bin/crowdsec, /usr/local/bin/cscli	github.com/crowdsecurity/crowdsec
google.golang.org/grpc	v1.79.1	/usr/bin/caddy	caddy

Verification: None of these packages appear in backend/go.mod, backend/go.sum, or the output of go mod graph.

Why grype dir:. Flags Module Cache Artifacts

Running grype dir:. over the Charon workspace also scans .cache/go/pkg/mod/ — the local Go module download cache. This directory contains the go.mod files of every transitively downloaded module. Grype reads those go.mod files and flags vulnerable version references within them, even though those versions are not compiled into the Charon binary. All module-cache findings have locations beginning with /.cache/go/pkg/mod/ and are not exploitable in Charon.

Stale SBOM: sbom-generated.json

sbom-generated.json (dated 2026-02-21) was generated by an earlier workflow before the grpc bump and uses a format with no version or PURL data. Grype reading this file matches vulnerabilities against package names alone with no version filter, inflating findings. The authoritative SBOM is sbom.cyclonedx.json (dated 2026-03-18, generated by Syft 1.42.2).

3. Actionable Findings

3.1 Stdlib CVEs in Stale Charon Binaries (Critical/High)

Grype found Charon binaries on-disk compiled with old Go versions. The current toolchain is go1.26.1, which patches all of the following.

Binary	Go Version	Notable CVEs
.trivy_logs/charon_binary	go1.25.4 (Nov 2025 artifact)	CVE-2025-68121 (Critical), CVE-2025-61726/29/31/32 (High)
backend/bin/charon, backend/bin/api, backend/bin/charon-debug	go1.25.6	CVE-2025-68121 (Critical), CVE-2025-61732 (High), CVE-2026-25679 (High)
backend/api (root-level)	go1.25.7	CVE-2026-25679 (High), CVE-2026-27142 (Medium)

CVE-2025-68121 (Critical, Go stdlib) is the single highest-severity finding in this report.

Remediation: Rebuild all binaries with go1.26.1. Delete .trivy_logs/charon_binary (stale Nov 2025 artifact) or add .trivy_logs/ to .gitignore.

3.3 Module Cache False Positives (All Confirmed Non-Exploitable)

Flagged solely because they appear in go.mod files inside .cache/go/pkg/mod/, not in any compiled Charon binary:

ID	Package	Flagged Version	Cache Source	Actual Charon Version
GHSA-p77j-4mvh-x3m3 (Critical)	google.golang.org/grpc	v1.67.0	containerd/errdefs/go.mod	v1.79.3
GHSA-9h8m-3fm2-qjrq (High)	go.opentelemetry.io/otel/sdk	v1.38.0	otelhttp@v0.63.0/go.mod	v1.42.0
GHSA-47m2-4cr7-mhcw (High)	github.com/quic-go/quic-go	v0.54.0	gin-gonic/gin@v1.11.0/go.mod	not a direct dep
GHSA-hcg3-q754-cr77 (High)	golang.org/x/crypto	v0.26.0	quic-go@v0.54.1/go.mod	v0.46.0
GHSA-cxww-7g56-2vh6 (High)	actions/download-artifact	v4	docker/docker GH workflows in cache	N/A

4. Scan Configuration Recommendations

Exclude Go Module Cache from grype dir:.

Create .grype.yaml at project root:

ignore:
  - package:
      location: "**/.cache/**"
  - package:
      location: "**/node_modules/**"

Alternatively, scan the SBOM directly rather than the filesystem: grype sbom:sbom.cyclonedx.json.

Regenerate or Remove sbom-generated.json

sbom-generated.json (Feb 21 2026) contains packages with no version or PURL data, causing name-only vulnerability matching. Delete it or regenerate with: syft scan dir:. -o cyclonedx-json > sbom-generated.json.

Delete or Gitignore .trivy_logs/charon_binary

The 23MB stale binary .trivy_logs/charon_binary (go1.25.4, Nov 2025) is a Trivy scan artifact causing several Critical/High CVE findings. Add .trivy_logs/*.binary or the whole .trivy_logs/ directory to .gitignore.
