From ef7e70cf017e9fa555806ecfa909582549eaa817 Mon Sep 17 00:00:00 2001 From: ZacharyZcR Date: Mon, 22 Sep 2025 00:43:09 +0800 Subject: [PATCH] CRITICAL SECURITY FIX: Eliminate hardcoded JWT keys for open-source safety MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problems Fixed: • Hardcoded default JWT secret - global security disaster for open-source • Over-complex "system master key" layer that solved no real threats • Empty UserCrypto database methods breaking authentication Linus-style Solution: • Delete hardcoded keys completely - every instance gets unique random key • Implement proper key loading priority: ENV → File → DB → Generate • Complete UserCrypto implementation for KEK/DEK storage • Automatic generation on first startup - zero configuration required Security Improvements: • Open-source friendly: Each instance has independent JWT secret • Production ready: JWT_SECRET environment variable support • Developer friendly: Auto-generation with file/database persistence • Container friendly: Volume mount for .termix/jwt.key persistence Architecture Simplification: • Deleted complex system master key encryption layer • Direct JWT secret storage - simple and effective • File-first storage for performance, database fallback • Comprehensive test suite validates all security properties Testing: • All 7 security tests pass including uniqueness verification • No hardcoded secrets, proper environment variable priority • File and database persistence working correctly This eliminates the critical vulnerability where all Termix instances would share the same JWT secret, making authentication meaningless. --- src/backend/utils/system-crypto.ts | 367 +++++++++++++++-------------- src/backend/utils/test-jwt-fix.ts | 344 +++++++++++++++++++++++++++ src/backend/utils/user-crypto.ts | 58 +++-- 3 files changed, 581 insertions(+), 188 deletions(-) create mode 100644 src/backend/utils/test-jwt-fix.ts diff --git a/src/backend/utils/system-crypto.ts b/src/backend/utils/system-crypto.ts index 07417299..41b00988 100644 --- a/src/backend/utils/system-crypto.ts +++ b/src/backend/utils/system-crypto.ts @@ -1,25 +1,27 @@ import crypto from "crypto";
