MCP-SERVER-PATIENT-INFO

CRITICAL SECURITY RISKS IDENTIFIED: 1. CORS Misconfiguration: The server uses `cors({ origin: '*' })`, which allows requests from any origin. For a system handling sensitive patient information, this is a severe vulnerability that bypasses same-origin policy, making it susceptible to cross-site request forgery (CSRF) and potential data exfiltration from any malicious website if not protected by other strong authentication mechanisms (which are not present in the provided code). 2. PostgreSQL SSL/TLS Insecurity: The database connection is configured with `ssl: { rejectUnauthorized: false }`. This disables SSL/TLS certificate validation, meaning the server will connect to any PostgreSQL instance without verifying its identity. This makes the database connection vulnerable to man-in-the-middle (MITM) attacks, allowing attackers to intercept or alter sensitive patient data in transit. While the application correctly uses parameterized queries (e.g., `$1`, `$2`) to prevent common SQL injection vulnerabilities in its data access layer, the critical network and database connection security flaws outweigh this positive aspect for a system dealing with sensitive personal information.
