Backend logs show requests alternating between two ingress source IPs (10.208.150.130 and 10.208.130.66), so identifier `{request.client.host}:{email}` rotates between values and the count for any single identifier never reaches 5. Result: 5-attempt lockout is effectively bypassed in production. Fix: derive client IP from X-Forwarded-For (e.g., first IP) before falling back to request.client.host, or key brute-force only by lowercased email.",

  "rca_of_the_issue": "Brute force lockout failure RCA: server.py line 234 uses `request.client.host` to build the rate-limit identifier. In the k8s preview deployment, the ingress fans out across multiple pods so requests from a single external client are seen alternately as 10.208.150.130 and 10.208.130.66 (confirmed in /var/log/supervisor/backend.out.log). Each identifier accumulates ~3 of 6 attempts -> never crosses the 5-fail threshold -> all 6 stay 401 instead of 5x401 + 429. Reproduction: POST /api/auth/login with same email + wrong password 6 times via the public preview URL. Mitigation: parse X-Forwarded-For (split on comma, take first) and fall back to request.client.host; or simply use email-only as identifier (small DoS risk against legitimate users mitigated by short 15-min window)."
