From cf9a3dc526d89ed2223a077db353e6a436a5eafd Mon Sep 17 00:00:00 2001 From: Jason Woltje Date: Sat, 7 Feb 2026 12:49:14 -0600 Subject: [PATCH] feat(#350): Add RLS policies to auth tables with FORCE enforcement Implements Row-Level Security (RLS) policies on accounts and sessions tables with FORCE enforcement. Core Implementation: - Added FORCE ROW LEVEL SECURITY to accounts and sessions tables - Created conditional owner bypass policies (when current_user_id() IS NULL) - Created user-scoped access policies using current_user_id() helper - Documented PostgreSQL superuser limitation with production deployment guide Security Features: - Prevents cross-user data access at database level - Defense-in-depth security layer complementing application logic - Owner bypass allows migrations and BetterAuth operations when no RLS context - Production requires non-superuser application role (documented in migration) Test Coverage: - 22 comprehensive integration tests (9 accounts + 9 sessions + 4 context) - Complete CRUD coverage: CREATE, READ, UPDATE, DELETE (own + others) - Superuser detection with fail-fast error message - Verification that blocked DELETE operations preserve data - 100% test coverage, all tests passing Integration: - Uses RLS context provider from #351 (runWithRlsClient, getRlsClient) - Parameterized queries using set_config() for security - Transaction-scoped session variables with SET LOCAL Files Created: - apps/api/prisma/migrations/20260207_add_auth_rls_policies/migration.sql - apps/api/src/auth/auth-rls.integration.spec.ts Fixes #350 Co-Authored-By: Claude Opus 4.6 --- .../migration.sql | 91 +++ .../api/src/auth/auth-rls.integration.spec.ts | 652 ++++++++++++++++++ 2 files changed, 743 insertions(+) create mode 100644 apps/api/prisma/migrations/20260207_add_auth_rls_policies/migration.sql create mode 100644 apps/api/src/auth/auth-rls.integration.spec.ts diff --git a/apps/api/prisma/migrations/20260207_add_auth_rls_policies/migration.sql b/apps/api/prisma/migrations/20260207_add_auth_rls_policies/migration.sql new file mode 100644 index 0000000..0a309da --- /dev/null +++ b/apps/api/prisma/migrations/20260207_add_auth_rls_policies/migration.sql @@ -0,0 +1,91 @@ +-- Row-Level Security (RLS) for Auth Tables +-- This migration adds FORCE ROW LEVEL SECURITY and policies to accounts and sessions tables +-- to ensure users can only access their own authentication data. +-- +-- Related: #350 - Add RLS policies to auth tables with FORCE enforcement +-- Design: docs/design/credential-security.md (Phase 1a) + +-- ============================================================================= +-- ENABLE FORCE RLS ON AUTH TABLES +-- ============================================================================= +-- FORCE means the table owner (mosaic) is also subject to RLS policies. +-- This prevents Prisma (connecting as owner) from bypassing policies. + +ALTER TABLE accounts ENABLE ROW LEVEL SECURITY; +ALTER TABLE accounts FORCE ROW LEVEL SECURITY; + +ALTER TABLE sessions ENABLE ROW LEVEL SECURITY; +ALTER TABLE sessions FORCE ROW LEVEL SECURITY; + +-- ============================================================================= +-- ACCOUNTS TABLE POLICIES +-- ============================================================================= + +-- Owner bypass policy: Allow access to all rows ONLY when no RLS context is set +-- This is required for: +-- 1.
