pluggedin-app

The application exhibits a robust security posture, incorporating numerous defense-in-depth measures. Key strengths include: comprehensive input validation and sanitization (URLs, paths, external IDs, HTML content) to prevent XSS, path traversal, and SSRF attacks; strong authentication security with bcrypt (cost factor 14), brute-force protection (account lockout), and detailed audit logging; secure session management with JWTs, periodic revalidation, and session invalidation on password changes; robust data encryption (AES-256-GCM with scrypt and random salts) for sensitive data at rest; global CSRF protection and HTTP security headers (CSP with nonce, X-Frame-Options, X-Content-Type-Options, etc.); and critical sandboxing capabilities for executing external MCP server code via Bubblewrap/Firejail for process, filesystem, and network isolation. While in-memory rate limiting is noted as a 'CRITICAL TODO' for multi-instance deployments in one file, other files show the use of `ioredis` for distributed rate limiting, mitigating this, though fallback to in-memory still presents a risk if Redis fails. `process.setMaxListeners` is used, which is a practical mitigation but could be a resource exhaustion vector if many STDIO servers are connected concurrently without proper scaling.
