Cerberus Fixes Verification

Date: December 12, 2025 QA Agent: QA_Security Status: ✅ PASS

Test Summary

Check	Result	Details
Backend Tests	✅ PASS	All packages pass, 85.1% coverage (≥85% required)
Frontend Tests	⚠️ PASS*	83/84 test files pass, 727/730 tests pass
Frontend Build	✅ PASS	Production build successful
Pre-commit	✅ PASS	All hooks pass

*Note: 1 flaky test in LiveLogViewer.test.tsx (WebSocket timing issue, not related to Cerberus)

Issue Fix Verification

Issue 1: Cerberus Default State in Feature Flags

File: feature_flags_handler.go

✅ VERIFIED - Line 32:

"feature.cerberus.enabled": false, // Cerberus OFF by default

Issue 2: Security Handler Reads Correct Setting Key

File: security_handler.go

✅ VERIFIED - Line 38:

var settingKey = "feature.cerberus.enabled"

The handler correctly reads from feature.cerberus.enabled (not an incorrect key).

Issue 3: Docker Compose Files Have CrowdSec Disabled

✅ VERIFIED - Found in:

• docker-compose.local.yml:25 - CHARON_SECURITY_CROWDSEC_MODE=disabled
• docker-compose.override.yml:25 - CHARON_SECURITY_CROWDSEC_MODE=disabled
• docker-compose.yml:25 - Commented template with disabled option
• docker-compose.dev.yml:25 - Commented template with disabled option

Cerberus Fixes Conclusion

All three Cerberus-related fixes have been verified:

1. ✅ Feature flags default feature.cerberus.enabled to false
2. ✅ Security handler reads from correct setting key feature.cerberus.enabled
3. ✅ Docker compose files set CROWDSEC_MODE=disabled in active configurations

Cerberus Verification: PASS

Import Modal and Certificate Status Card Features

Date: December 11, 2025 Auditor: QA_Security Agent Overall Status: ⚠️ PARTIAL PASS

Executive Summary

The import modal (ImportSuccessModal) and certificate status card (CertificateStatusCard) features have been audited for code quality, type safety, accessibility, and proper testing. The core features are well-implemented with comprehensive test coverage, but there are 5 failing tests in CrowdSecConfig (unrelated to the audited features) that need attention.

Test Results Summary

1. TypeScript Type Check ✅ PASS

npm run type-check - Passed
No TypeScript errors detected

2. Frontend Tests with Coverage ⚠️ PARTIAL PASS

Test Files: 82 passed, 2 failed (84 total)
Tests: 723 passed, 5 failed, 2 skipped (730 total)

Failed Tests (in CrowdSecConfig - not related to audited features):

• CrowdSecConfig.coverage.test.tsx: 3 failures
  • auto-selects first preset and pulls preview - Element not found preset-select

Code Review: ImportSuccessModal

File: frontend/src/components/dialogs/ImportSuccessModal.tsx

✅ Strengths

1. Type Safety

   • Well-defined ImportSuccessModalProps interface
   • Explicit typing for all props including results structure
   • Null safety with early return when !visible || !results

2. Error Handling

   • Dedicated error section with proper conditional rendering
   • Scrollable error list with max-h-24 overflow-y-auto
   • Clear error count display with proper pluralization

3. Accessibility

   • Backdrop click to close modal
   • Clear visual hierarchy with icons (CheckCircle, AlertCircle, Info)
   • Focus-visible button styles with transition-colors

4. Styling Consistency

   • Uses project's design tokens (bg-dark-card, bg-blue-active)
   • Responsive layout with flex-wrap and max-w-full mx-4
   • Consistent spacing and color scheme

5. Memory/Cleanup

   • No subscriptions or event listeners to clean up
   • Pure functional component with no side effects

⚠️ Recommendations

1. Accessibility Enhancement
   • Add role="dialog" and aria-modal="true" to modal container
   • Add aria-labelledby pointing to title element
   • Consider focus trapping for keyboard navigation

// Recommended enhancement:
<div
  className="relative bg-dark-card rounded-lg..."
  role="dialog"
  aria-modal="true"
  aria-labelledby="import-modal-title"
>
  <h2 id="import-modal-title" className="text-xl font-bold text-white">
    Import Completed
  </h2>

2. Keyboard Support
   • Add onKeyDown handler for Escape key to close modal

Code Review: CertificateStatusCard

File: frontend/src/components/CertificateStatusCard.tsx

✅ Strengths

1. Type Safety

   • Uses imported Certificate and ProxyHost types
   • Clean interface definition for props
   • No any types used

2. Computed Values

   • Efficient calculation of certificate status counts
   • Smart pending detection logic (SSL forced + enabled + no cert)
   • Progress percentage with edge case handling (empty array = 100%)

3. Accessibility

   • Uses Link component for navigation (accessible by default)
   • Visible focus states inherited from router Link

4. Styling Consistency

   • Follows card design pattern used elsewhere
   • Responsive hover transitions
   • Animated spinner for pending state (animate-spin)

5. Memory/Cleanup

   • Stateless functional component
   • No subscriptions or event listeners

✅ No Issues Found

The component is clean, well-typed, and follows best practices.

---

Code Review: useImport Hook

File: frontend/src/hooks/useImport.ts

✅ Strengths

1. State Management

   • Proper use of useState for local state (commitSucceeded, commitResult)
   • Correct query invalidation patterns
   • Smart polling logic with refetchInterval

2. Error Handling

   • Comprehensive error aggregation from multiple sources
   • Guards against 404 errors after commit (expected behavior)
   • Clear error message extraction

3. Memory/Cleanup

   • React Query handles cleanup automatically
   • Proper cache removal with removeQueries on success/cancel
   • clearCommitResult function for state reset

4. Type Safety

   • Explicit type imports
   • Type re-exports for consumers

---

Test Coverage Analysis

ImportSuccessModal.test.tsx ✅

• 12 tests covering all major functionality
• Tests for rendering, user interactions, and edge cases
• Proper mock setup with vi.fn()
• Grammar tests (singular/plural)
• Visibility/null result tests

CertificateStatusCard.test.tsx ✅

• 14 tests covering all states
• Router wrapper setup correct
• Progress calculation tests
• Edge cases (empty arrays, disabled hosts, no SSL)
• Link destination verification

---

Issues Found (Unrelated to Audited Features)

CrowdSecConfig Test Failures

The failing tests are in CrowdSecConfig.spec.tsx and CrowdSecConfig.coverage.test.tsx. The issues are:

1. Element selection conflict: Tests use screen.getByRole('textbox') but the component now has multiple textbox elements (search input + textarea)
2. Missing preset-select testid: Some tests expect a data-testid="preset-select" element that may have been refactored

Recommendation: Update CrowdSecConfig tests to use more specific selectors:

// Instead of:
const textarea = screen.getByRole('textbox')
// Use:
const textarea = screen.getByTestId('crowdsec-file-textarea')
// Or:
const textarea = screen.getAllByRole('textbox')[1] // if order is consistent

Recommendations

1. High Priority: Fix the 5 failing CrowdSecConfig tests by updating element selectors
2. Medium Priority: Add ARIA attributes to ImportSuccessModal for better accessibility
3. Low Priority: Address ESLint warnings in CrowdSecConfig.tsx (missing deps, any types)

---

Conclusion

PARTIAL PASS - The audited features (ImportSuccessModal, CertificateStatusCard, useImport) are well-implemented and pass all their tests. The failing tests are in an unrelated component (CrowdSecConfig) and should be addressed in a separate PR.

The code demonstrates:

• Strong TypeScript usage
• Comprehensive test coverage for the audited features
• Consistent styling patterns
• Proper React Query patterns
• No memory leaks or cleanup issues
