Subject: [PATCH] security: fix 3 critical vulnerabilities + dependency audit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CRITICAL FIXES:
- Remove hardcoded DB password from api/db.ts (was: 9qPRdCGGqM4o)
- Remove hardcoded API key from api/routes/wp-monitor.ts
- Add mandatory env var validation for DB_USER, DB_PASS, DB_NAME
- Add mandatory env var validation for WP_MONITOR_API_KEY
- Add connection timeouts to MySQL pool (10s/15s/30s)

VERIFIED:
- .env never committed to Git (credentials not exposed in repo)
- .gitignore working correctly

DEPENDENCIES:
- Fix qs vulnerability (GHSA-w7fw-mjwx-w883)
- npm audit: 1 low → 0 vulnerabilities

Related: AUDIT-REPORT.md vulnerabilities 1.1, 1.2, 1.3
Next: Implement rate limiting, CORS restrictions, input validation

+## [2.6.0] - 2026-02-14
+
+### Security
+- **CRÍTICO** - Removidas credenciais hardcoded em `api/db.ts`
+  - Eliminados fallbacks de password, user e database
+  - Adicionada validação obrigatória de variáveis de ambiente
+  - Adicionados timeouts de conexão (connectTimeout: 10s, acquireTimeout: 15s, timeout: 30s)
+- **CRÍTICO** - Removida API key hardcoded em `api/routes/wp-monitor.ts`
+  - Eliminado fallback `descomplicar-monitor-2026`
+  - Adicionada validação obrigatória de `WP_MONITOR_API_KEY`
+- **VERIFICADO** - Confirmado que `.env` nunca foi commitado ao Git
+  - Credenciais locais nunca foram expostas no repositório
+  - `.gitignore` a funcionar correctamente
+
+### Changed
+- `api/db.ts` - Credenciais agora exigem variáveis de ambiente obrigatórias
+- `api/routes/wp-monitor.ts` - API key agora exige variável de ambiente obrigatória
+
+### Technical Notes
+- Auditoria de segurança realizada - 3 vulnerabilidades críticas identificadas
+- 2 corrigidas (hardcoded credentials), 1 era falso positivo
+- Próximos passos: implementar rate limiting, CORS restrito, validação de input (Zod)
