Context

/auth/login and /auth/register have no protection against brute-force or automated abuse. An attacker can make unlimited requests with no throttling.

Roadmap reference: ROADMAP.md > P1 > Error handling and resilience > No rate limiting on auth endpoints

What to do

  1. Add a rate-limiting middleware or decorator (e.g. slowapi for FastAPI) to the project.
  2. Apply a sensible default limit to /auth/login (e.g. 10 requests/minute per IP) and /auth/register (e.g. 5 requests/minute per IP).
  3. Make the limits configurable via environment variables (AUTH_RATE_LIMIT_LOGIN, AUTH_RATE_LIMIT_REGISTER).
  4. Return HTTP 429 with a Retry-After header when the limit is exceeded.
  5. Add integration tests that verify 429 is returned after the threshold is crossed.

Acceptance criteria

  • Exceeding the configured rate limit on /auth/login returns HTTP 429.
  • Limits are configurable via env vars.
  • At least one test covers the rate-limit response.
