Hard-coded secrets
AI assistants happily inline API keys and connection strings to make code run. We scan your deployed app for exposed keys in the common formats.
// Cursor security
Cursor wrote the code. Who checked the security? you can.
Cursor is an AI code editor, not a host — so the security of your app depends on what it generated and where you deployed it. AI-written code tends to repeat the same insecure patterns.
Scan your Cursor app now — free, ~60 seconds, no signup.
Cursor accelerates writing code, which means it also accelerates shipping the insecure parts: secrets pasted into source, endpoints with no input validation, auth that checks the wrong thing, and dependencies with known holes.
Because Cursor apps deploy anywhere — Vercel, Netlify, a VPS, with Supabase or Firebase behind them — the right check is on the live URL, looking at what's actually exposed rather than the editor itself.

What goes wrong on Cursor
Missing input validation
Generated endpoints often trust their inputs, opening the door to injection. Our deep scan sends safe probes for SQLi and XSS patterns.
Broken access control
Auth that checks 'is logged in' but not 'owns this resource' lets any user read others' data (IDOR). We surface the surface area; a human audit confirms it.
Vulnerable dependencies
AI-suggested package versions are often outdated. We check your front-end libraries against known CVEs.
Your Cursor security checklist
- No secrets in source — use environment variables
- Every input is validated and parameterised
- Access control checks ownership, not just authentication
- Dependencies updated past known CVEs
- Security headers set on the deployed app
- Backend (Supabase/Firebase) rules locked down
Cursor security FAQ
Is code from Cursor secure?
Cursor writes correct, working code — but it optimises for getting things done, not for security review. Hard-coded secrets, missing validation, and broken access control are common. Review and scan before shipping.
Cursor is just an editor — what should I scan?
Scan the live app you deployed. The vulnerabilities live in the running code and its backend, not in the editor. bleek checks the URL.
How do I check my app?
Paste your deployed URL into bleek's free scan for exposed secrets, missing headers, and open backends — and enable Deep Scan for active injection and auth-bypass probes.
