1. Missing Rate Limiting (js/missing-rate-limiting)
   • Location: src/server/Server.js:79
   • Severity: Medium
   • Status: Acknowledged - Not fixed for this demo/development version
   • Details: The file serving route handler is not rate-limited
   • Recommendation: For production deployment, add rate limiting middleware like express-rate-limit

const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

this.app.use(limiter);

All dependencies are secure and up-to-date.

1. Input Validation: User input is validated in the /api/process endpoint
2. Error Handling: Try-catch blocks implemented for async operations
3. WebSocket Security: Origin validation can be added for production
4. No Hardcoded Secrets: Configuration uses environment variables via dotenv
5. CORS Configuration: CORS middleware properly configured

1. Add rate limiting to all routes
2. Implement authentication/authorization
3. Add input sanitization
4. Enable HTTPS/TLS
5. Add WebSocket origin validation
6. Implement request size limits
7. Add logging and monitoring
8. Use helmet.js for additional security headers
9. Implement CSP (Content Security Policy)
10. Add database security if data persistence is added
