Summary

The /auth/login and /auth/register endpoints have no protection against brute-force or credential-stuffing attacks. A middleware or per-route limiter is needed.

Work

  • Add a rate limiting library (e.g., slowapi which integrates with FastAPI/Starlette) as a dependency.
  • Apply a strict limit to /auth/login (e.g., 10 requests / minute per IP).
  • Apply a looser limit to /auth/register (e.g., 5 requests / minute per IP).
  • Return 429 Too Many Requests with a Retry-After header when the limit is exceeded.
  • Make the rate limit values configurable via environment variables.

Acceptance Criteria

  • Sending more than the configured number of requests per minute to /auth/login returns 429.
  • Legitimate requests within the limit succeed normally.
  • Rate limit thresholds are documented in .env.example.

## Summary The `/auth/login` and `/auth/register` endpoints have no protection against brute-force or credential-stuffing attacks. A middleware or per-route limiter is needed. ## Work - Add a rate limiting library (e.g., `slowapi` which integrates with FastAPI/Starlette) as a dependency. - Apply a strict limit to `/auth/login` (e.g., 10 requests / minute per IP). - Apply a looser limit to `/auth/register` (e.g., 5 requests / minute per IP). - Return `429 Too Many Requests` with a `Retry-After` header when the limit is exceeded. - Make the rate limit values configurable via environment variables. ## Acceptance Criteria - Sending more than the configured number of requests per minute to `/auth/login` returns `429`. - Legitimate requests within the limit succeed normally. - Rate limit thresholds are documented in `.env.example`.

Triage (Repo Manager): Delegating to @security-reviewer. This is a P1 security task adding rate limiting to auth endpoints. Requires adding a dependency (slowapi) and configuring per-route limits.
