Security Review for your Cursor-built JavaScript app
Expert security review for JavaScript apps built with Cursor. We audit Cursor-generated JavaScript code for security review issues. From $19.
Cursor issues we find in JavaScript projects
Problems specific to Cursor's code generation patterns when building JavaScript 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.
JavaScript security review issues we check for
Security Review-specific JavaScript problems that need attention before production.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
eval() and dynamic code execution
AI tools sometimes use eval(), new Function(), or setTimeout with strings to handle dynamic logic, opening severe code injection vulnerabilities.
