The application uses express.json() and express.urlencoded() but does not apply any input validation or sanitization middleware (e.g., express-validator, zod schemas on request bodies). The TODO comments confirm that input validation is planned but not implemented. This leaves the application vulnerable to injection attacks and malformed data.
ImpactAn attacker could send malicious payloads in request bodies or query parameters, potentially leading to NoSQL injection (if using MongoDB), SQL injection (if raw queries are used), or other injection attacks. Additionally, missing validation could allow unexpected data types to cause application errors or logic flaws.
FixImplement input validation middleware using libraries like express-validator or zod. Validate all request bodies, query parameters, and path parameters against defined schemas before passing to controllers.
24app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument));// Network-exposed MCP server; documentation aids attackers.
The Swagger UI documentation is exposed at /api-docs without any authentication. While this is not a vulnerability per se, it provides an attacker with a complete map of all API endpoints, request formats, and data schemas, making it easier to craft attacks.
ImpactAn attacker can discover all API endpoints and their parameters, facilitating targeted attacks against the API.
FixRestrict access to /api-docs in production, either by removing it or adding authentication middleware before the Swagger UI route.
