For Cursor users

Is your Cursor app secure?

Cursor helps you ship fast. But AI-generated code often ships with hardcoded API keys, missing security headers, and injection vulnerabilities you never wrote yourself.

Scan your deployed app or paste code — free, no account needed.

What Cursor apps commonly leak

Hardcoded OpenAI, Stripe, Supabase, and GitHub API keys
Missing Content-Security-Policy headers — XSS wide open
Environment variables committed to client-side code
Insecure cookie flags (no HttpOnly, no Secure)
CORS misconfigurations from AI-suggested defaults
Exposed .env files and configuration backups
Server info leakage (version numbers, tech stack)
InnerHTML XSS from AI-generated JavaScript patterns

Common questions

Is Cursor code less secure than hand-written code?▾

Not inherently — but AI coding tools generate code from patterns in their training data, which includes insecure examples. Cursor doesn't know your security requirements. It will happily generate code with hardcoded keys if that pattern appears in its training data. The developer is still responsible for security — the scanner catches what gets missed.

Does scanning my Cursor app cost anything?▾

No. First scan is free with no account needed. Sign up for a free account and get 3 scans per day plus AI fix prompts formatted for Cursor.

Do fix prompts actually work in Cursor Composer?▾

Yes. Generated prompts include the file path, line number, current code, and the exact fix needed. Paste into Cursor Composer and it applies the fix. Tested with Cursor 0.44+.

Can I scan code before deploying?▾

Yes. Use the Code mode in the scanner — paste your code directly and get results before it hits production. Works for TypeScript, JavaScript, Python, and more.

What if Cursor's API key is in my code?▾

The scanner redacts secrets automatically. Raw keys are replaced with [REDACTED] in stored results. Your evidence is safe even if the finding is shared.
