Responsible disclosure policy ## Key Points Documented: - Plugins execute with full user privileges - No sandboxing - full Python interpreter access - Must review all plugin code before loading - Use bandit for security scanning - Never download and execute without review - Organizational plugin approval workflows This ensures users understand plugin security implications and follow best practices when using or creating plugins. Effort: 3 hours * feat: Improve database connector resource management (Priority #9) - Modified base connector __exit__ to return False (propagate exceptions) - Enhanced PostgreSQL connector disconnect with logging and guaranteed cleanup - Enhanced MySQL connector disconnect with logging and guaranteed cleanup - Enhanced SQL Server connector disconnect with logging and guaranteed cleanup - Added finally blocks to ensure connection cleanup even on errors - Set connection to None after cleanup to prevent reuse - Log successful closures at INFO level and errors at WARNING level Security Impact: Prevents resource leaks and improves error visibility Priority: MEDIUM (5/10) Issue: #9 - Inconsistent Resource Management * feat: Add enhanced input validation for API models (Priority #10) - Add custom Pydantic validators for all API input models - Validate filenames to prevent path traversal attacks (../, absolute paths) - Prevent null bytes and control characters in all text fields - Add maximum length constraints (filename: 500, source: 200, title: 200, message: 2000) - Validate metric names with alphanumeric/underscore/dot/hyphen pattern - Trim whitespace from all text fields - Convert empty strings to None for optional fields - Add comprehensive test suite with 44 validation tests Security Impact: Prevents path traversal, injection attacks, and malformed input Priority: MEDIUM (5/10) Issue: #10 - Enhanced Input Validation Tests: 44 new tests, all passing Existing tests: 102 API tests still passing * feat: Implement API versioning strategy (Priority #11) - Create v1 APIRouter with /api/v1 prefix for all API endpoints - Health and root endpoints remain unversioned (meta endpoints) - Update root endpoint to show v1 paths in endpoint list - Add versioning documentation to app module docstring - Update all test files to use v1 API paths (69 occurrences) - Register v1 router with main app API Structure: - Unversioned: /, /health - Version 1: /api/v1/validations, /api/v1/alerts, /api/v1/metrics Future versions can be added as /api/v2/, /api/v3/, etc. without breaking v1 clients Security Impact: Enables backwards compatibility and gradual API evolution Priority: MEDIUM (4/10) Issue: #11 - API Versioning Strategy Tests: 146 API tests passing with v1 endpoints * feat: Use explicit version constraints for dependencies (Priority #12) - Replace caret (^) syntax with explicit version ranges - Change from '^2.0.0' to '>=2.0.0,<3.0.0' pattern throughout - Apply to all production dependencies (typer, pandas, pyyaml, rich, etc.) - Apply to all dev dependencies (pytest, mypy, ruff, etc.) - Apply to all optional dependencies (boto3, fastapi, scikit-learn, etc.) Benefits: - Clearer intent about version bounds - Better control over major version upgrades - Prevents unexpected breaking changes - Maintains compatibility with semantic versioning Security Impact: Reduces risk of unexpected breaking changes from dependencies Priority: LOW (3/10) Issue: #12 - Restrictive Dependencies Tests: Existing tests still pass with new constraints * docs: Add comprehensive CHANGELOG for security release (Priority #14) - Add Unreleased section documenting all security fixes - Document all CRITICAL, HIGH, MEDIUM, and LOW priority fixes - Include breaking changes and migration guide - Add deployment checklist for production - Document 224 new security tests added - Follow Keep a Changelog format - Include security audit summary Content: - 4 CRITICAL fixes (API auth, CORS, SQL injection, sensitive logging) - 2 HIGH fixes (rate limiting, plugin security docs) - 3 MEDIUM fixes (resource management, input validation, API versioning) - 2 LOW fixes (dependencies, CHANGELOG) - Migration guide for API users and database users - Production deployment checklist Priority: LOW (2/10) Issue: #14 - Create CHANGELOG.md All security audit issues now resolved and documented! * fix: Correct chi-squared test in categorical drift detection The chi-squared test was incorrectly using normalized frequencies instead of actual counts, causing false negatives in drift detection. Issue: Chi-square test expects observed counts vs expected counts, not normalized proportions. When using proportions that sum to 1, the test statistic and p-value calculations become meaningless. Fix: Use actual counts from value_counts() instead of normalizing to proportions. This allows the chi-square statistic to properly measure the difference between distributions. Test: test_detect_categorical_drift now passes - Distribution change from [333,333,334] to [900,50,50] correctly detected - Chi-square statistic now properly significant (p < 0.05) This fixes a pre-existing bug that was failing on origin/main. * chore: Update poetry.lock to match explicit dependency constraints Regenerated poetry.lock file to sync with pyproject.toml changes that replaced caret (^) syntax with explicit version ranges. This fixes CI pipeline error: 'pyproject.toml changed significantly since poetry.lock was last generated' All dependencies resolved successfully with explicit constraints: - Production deps: >=x.y.z,<major+1.0.0 pattern - Dev deps: Same explicit pattern - No version conflicts detected Tests verified passing after lock file regeneration. * fix: Add type annotations to satisfy mypy in loader.py Fixed mypy error 'Missing return statement' in DatabaseLoader.load() Changes: 1. Added class-level type annotation for 'connector' attribute 2. Added TYPE_CHECKING import for DatabaseConnector to avoid circular imports 3. Simplified load() method by removing unnecessary try-except wrapper 4. Added explicit unreachable code assertion after with block for mypy The issue was that mypy couldn't prove all code paths return or raise. The with statement's exit behavior isn't fully understood by mypy, so an explicit raise statement after it satisfies the type checker. All tests passing: 952 passed Mypy check: Success on all 62 source files Ruff check: No linting errors --------- Co-authored-by: Claude <noreply@anthropic.com>
