Free Cursor security scanner
Cursor writes code fast, and you deploy it wherever you like. That flexibility means nothing is secure by default: the checks a hosted builder might do for you are now your job.
What we check on Cursor apps
Typical stack: Any stack — AI-written code you deploy yourself
A misconfigured server can serve your .env or your whole git history to anyone who asks. VibeShield checks for these and other sensitive files, and reports only that they're reachable — never their contents.
AI assistants happily inline an API key to get a demo working. VibeShield scans your shipped JavaScript and page data for real credentials.
“Access-Control-Allow-Origin: *” pasted in to fix a dev error, combined with credentials, turns your API into everyone's API.
No Content-Security-Policy, HSTS or clickjacking protection means one injected script or a framing attack goes unchecked. VibeShield tells you which headers are missing and what to set.
