- PKCE (S256) in OAuth flow: code_verifier in oauth_states, code_challenge in auth URL
- CryptoService: AES-256-GCM encryption for OAuth provider tokens at rest
- OAuth redirect URL validated against OAUTH_ALLOWED_REDIRECT_DOMAINS
- CHAT_JWT_SECRET must differ from JWT_SECRET in production
- Migration script: cmd/tools/encrypt_oauth_tokens for existing tokens
- Fixes: VEZA-SEC-003, VEZA-SEC-004, VEZA-SEC-009, VEZA-SEC-010
Add validation in ValidateForEnvironment() to fail startup when
CLAMAV_REQUIRED=false in production. Virus scanning is mandatory
for all file uploads in production.
Phase 1 audit - P1.4
- 1.6: Replace hardcoded JWT secrets in chat server tests with runtime-generated
values (env TEST_JWT_SECRET or uuid-based fallback)
- 1.7: Add validateNoBypassFlagsInProduction() in config; fail startup if
