Security Review for your Cursor-built Next.js app
Expert security review for Next.js apps built with Cursor. We audit Cursor-generated Next.js code for security review issues. From $19.
Cursor issues we find in Next.js projects
Problems specific to Cursor's code generation patterns when building Next.js apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Next.js security review issues we check for
Security Review-specific Next.js problems that need attention before production.
Unprotected API routes
Next.js API routes and server actions without authentication checks, allowing anyone to call them directly.
Server action data exposure
Server actions that return sensitive data to the client or don't validate user permissions before modifying data.
Incorrect middleware configuration
Auth middleware that doesn't cover all protected routes, uses wrong matchers, or can be bypassed with URL manipulation.
