Fix guides for Cursor
Common Cursor security fixes
Missing CSP header
A missing Content-Security-Policy header lets attackers inject scripts into your site. Here is what CSP does, why you need it, and how to add it in Next.js, Vercel, and Supabase apps.
Read moreMissing HSTS header
HSTS tells browsers to always use HTTPS for your site. Without it, users can be downgraded to HTTP and have sessions stolen. Here is how to add HSTS on Vercel, Next.js, and other hosts.
Read moreExposed .git directory
An exposed .git directory lets attackers download your entire source history, including deleted secrets. Here is how to check and fix it.
Read moreCookie missing Secure flag
Cookies without the Secure flag can be sent over HTTP, leaking session tokens to anyone on the same network. Here is how to set it.
Read moreCookie missing HttpOnly
HttpOnly stops JavaScript from reading a cookie, which is critical for session tokens. Here is when and how to set it.

Any secret in your client bundle is public. Here is how to find them, rotate them, and move the calls server-side.

Cursor security FAQ
- How do I use SafeToShip findings with Cursor?
- Each finding has an AI prompt written for Cursor. Paste it into Composer (or Chat with your codebase selected) and Cursor will make the fix across all relevant files.
- Does Cursor check security by default?
- Cursor has no built-in security scanning. It follows the patterns in your codebase — which often means it replicates security issues rather than fixing them.
