From 491993f9c1e8d6cffcd08eb1ff575aad378f502f Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Thu, 14 May 2026 04:52:31 +0300 Subject: [PATCH] [AZ-536] [AZ-537] [AZ-538] Argon2id, login rate limit + lockout, CORS https-only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit AZ-536 — replace unsalted SHA-384 password hashing with Argon2id (RFC 9106). Stored as PHC string with 64 MiB / 3 iter / 1 lane defaults; legacy SHA-384 hashes detected by prefix and lazily re-hashed on next successful login. Verify uses CryptographicOperations.FixedTimeEquals on both formats. AZ-537 — add per-IP sliding window rate limit on /login (ASP.NET Core RateLimiter, 10/60s default — production-tight) plus DB-backed per-account limit (5/300s) and consecutive-failure lockout (10 / 15 min) on the users row. Adds a generic audit_events table with INSERT/SELECT-only grants for the app role so the per-account count is queryable and admins cannot erase their own forensic trail. BusinessExceptionHandler maps AccountLocked to 423 and LoginRateLimited to 429, both with Retry-After. AZ-538 — drop the http://admin.azaion.com origin from CORS, gate UseHsts() + UseHttpsRedirection() to non-Development envs (1y / preload). Test infra: Npgsql in the e2e project + a DbHelper for direct DB inspection used by the AZ-536/537 ACs. appsettings.Development.json raises PerIpPermitLimit to 1000 so the suite (~270 logins from one container IP) doesn't false-trip the limiter. Tests: 53 pass + 3 documented skips (per-IP rate limit needs distinct client IPs; HSTS/HTTPS redirect need ASPNETCORE_ENVIRONMENT=Production). Code review: PASS_WITH_WARNINGS — 0 Critical, 0 High, 1 Medium, 3 Low. See _docs/03_implementation/reviews/batch_01_cycle2_review.md. Closes AZ-530 epic batch 1 of 4.
