Cursor Security Audit
Built your app with Cursor? We find the security issues AI missed.
Cursor is a popular AI-powered code editor that integrates LLMs directly into the development workflow. It offers tab completion, inline editing, and chat-based code generation. While it produces functional code quickly, security is often an afterthought in the generated output. Cursor-generated projects frequently ship with exposed API keys, missing input validation, and overly permissive database policies.
Common Cursor Security Issues
These are the vulnerabilities we most frequently find in Cursor-generated projects.
Exposed API keys in client-side code
criticalCursor frequently places API keys and secrets directly in frontend files or environment variables prefixed with NEXT_PUBLIC_, making them visible to anyone inspecting the browser.
Missing Row Level Security policies
criticalWhen generating Supabase schemas, Cursor often creates tables without enabling RLS or writes overly permissive policies that allow any authenticated user to read or modify all rows.
No server-side input validation
highForm handlers and API routes generated by Cursor typically trust client-side validation alone, with no server-side checks using libraries like Zod or Yup.
Insecure direct object references
highAPI endpoints often use user-supplied IDs without verifying that the requesting user has permission to access the resource, enabling horizontal privilege escalation.
Verbose error messages in production
mediumError handlers expose stack traces, database query details, and internal paths to end users instead of returning generic error messages.

Cursor Audit FAQ
Is Cursor code secure?
Cursor generates functional code quickly, but like all AI coding tools, it often prioritises getting things working over security best practices. Common issues include exposed API keys, missing input validation, and insecure database configurations. Our audits specifically target the patterns Cursor tends to produce.
What are common Cursor security issues?
The most frequent issues we find in Cursor projects include: exposed api keys in client-side code, missing row level security policies, no server-side input validation. These are well-documented patterns that our audit process specifically checks for.
Do I need an audit for my Cursor app?
If your Cursor app handles user data, payments, or any sensitive information, an audit is strongly recommended before going to production. Even simple apps can have critical vulnerabilities that AI tools introduce without warning. Our Security Scan package is a great starting point.
How long does a Cursor audit take?
Our Security Scan takes 3 business days, the Full Audit takes 7 business days, and the Production Ready package takes 10-12 business days. The timeline depends on the size and complexity of your codebase, not which tool generated it.
