This commit addresses all CRITICAL and MEDIUM security vulnerabilities
identified in the security audit with environment-aware configuration.
## Docker Compose Profiles
- Added docker-compose.dev.yml for development (relaxed security)
- Added docker-compose.prod.yml for production (strict security)
- Environment-specific configurations for rate limiting, CSRF, logging
## CRITICAL Fixes (P0)
1. Fixed insecure random number generation
- Replaced Math.random() with crypto.randomBytes() for verification codes
- Now cryptographically secure
2. Implemented rate limiting
- express-rate-limit for all endpoints
- Strict limits on auth endpoints (5 attempts in dev=off, prod=5)
- Email endpoint limits (20 in dev, 3 in prod)
- API-wide rate limiting
3. Added request body size limits
- Development: 50MB (for testing)
- Production: 10KB (security)
4. Fixed user enumeration vulnerability
- Generic error message for registration
- No disclosure of which field exists
5. Added security headers
- helmet.js with CSP, HSTS, XSS protection
- No-sniff, hide powered-by headers
## MEDIUM Fixes (P1)
6. Strengthened password policy
- Environment-aware validation (8+ chars)
- Production: requires uppercase, lowercase, number
- Development: relaxed for testing
7. Enhanced input validation
- Validation for all auth endpoints
- WSDC ID validation (numeric, max 10 digits)
- Name validation (safe characters only)
- Email normalization
8. Added input sanitization
- DOMPurify for XSS prevention
- Sanitize all user inputs in emails
- Timing-safe string comparison for tokens
9. Improved error handling
- Generic errors in production
- Detailed errors only in development
- Proper error logging
10. Enhanced CORS configuration
- Whitelist-based origin validation
- Environment-specific allowed origins
- Credentials support

- docs/SECURITY_AUDIT.md - Full security audit report
- .gitignore - Updated to exclude .env files
## Dependencies Added
- helmet (^8.1.0) - Security headers
- express-rate-limit (^8.2.1) - Rate limiting
- dompurify (^3.3.0) - XSS prevention
- jsdom (^27.2.0) - DOM manipulation for sanitization
## Testing
- ✅ Password validation works (weak passwords rejected)
- ✅ User enumeration fixed (generic error messages)
- ✅ WSDC lookup functional
- ✅ Registration flow working
- ✅ Rate limiting active (environment-aware)
- ✅ Security headers present
## Usage
Development:
docker compose -f docker-compose.yml -f docker-compose.dev.yml up
Production:
docker compose -f docker-compose.yml -f docker-compose.prod.yml up

Testing
Tests are written using:
- Jest - Test framework
- Supertest - HTTP assertions
Run tests:
npm test
Current test coverage:
- Health check endpoint
- 404 error handling
- CORS configuration
- JSON body parsing
Docker
Build and run with Docker Compose (from project root):
docker compose up --build
Backend will be available at:
- Internal: http://backend:3000
- Through nginx: http://localhost:8080/api
Next Steps
- ✅ Basic Express setup
- ✅ Health check endpoint
- ✅ Unit tests
- ⏳ PostgreSQL connection
- ⏳ Database schema and migrations
- ⏳ Authentication (JWT + bcrypt)
- ⏳ Socket.IO for real-time chat
- ⏳ WebRTC signaling
