Security & Code Audit for Node.js Projects

CodeAudit.dev checks your Node.js codebase for the vulnerabilities, performance issues, and architecture problems most common to Node.js applications.

Common Node.js Issues

Missing Helmet and essential security headers

Unvalidated request bodies and parameters

Synchronous blocking operations in the event loop

Outdated Express or Fastify middleware

Missing rate limiting on authentication routes

Insecure session management

Uncaught promise rejections and error mishandling

Example Finding

[High]

Missing Rate Limiting on Login Route

The authentication endpoint allows unlimited login attempts. This exposes the application to brute-force and credential-stuffing attacks.

Fix:Implement rate limiting using a middleware like express-rate-limit to restrict the number of failed attempts per IP address.

Why Node.js Projects Need Specialized Checks

Node.js is highly scalable, but its single-threaded nature means a single blocking operation can take down your entire service. Furthermore, building APIs requires rigorous input validation and secure configurations. CodeAudit inspects your Node.js code for event loop blockers, missing security headers, authentication flaws, and dependency vulnerabilities to keep your backend resilient.

Frequently Asked Questions

Do you support Express, NestJS, and Fastify?

Yes, CodeAudit recognizes the patterns and middlewares associated with all major Node.js frameworks.

Can it detect blocking synchronous operations?

Yes. We scan for synchronous filesystem or crypto operations that should be asynchronous to prevent event loop blocking.
