Security

  • All user-supplied URLs validated against SSRF (blocks private IPs, metadata endpoints, non-HTTP protocols)
  • Rate limiting on all routes (stricter on offensive tools)
  • CORS restricted to frontend origins only
  • JWT-based authentication with crypto password hashing
  • No secrets stored client-side
  • ErrorBoundary prevents white-screen crashes
  • window.open uses noopener throughout
  • Webhook relay headers whitelisted
  • Analytics tracking middleware (anonymous usage stats)
