Summary

No rate limiting exists on ANY federation endpoint. Public endpoints completely unprotected against DoS attacks.

Security Impact

  • Connection flood attacks
  • Command spam attacks
  • Agent spawn abuse
  • Signature verification DoS (expensive RSA operations)
  • Database exhaustion

Required Implementation

  1. Install @nestjs/throttler package
  2. Configure global throttler module
  3. Apply @Throttle() decorators to all endpoints
  4. Different limits per endpoint (10-100/minute)

Files Affected

All controllers in apps/api/src/federation/

Priority

CRITICAL (P0) - Blocks production deployment
