Security Audit for
Cursor-Built Apps
Cursor ships your app fast. SecuriSky finds what it left vulnerable. Scan your deployed app in 60 seconds — then paste the fix prompts straight back into Cursor Agent.
No signup. No source code. Instant results.
What Cursor doesn't catch
These are deployment-time issues that even the best AI code generator misses — because they require scanning the live, running application.
API Keys in Client Bundles
Cursor often puts credentials in .env.local and uses them in shared modules. The result: secrets end up in your JavaScript bundle visible to any user.
Missing Security Headers
Cursor doesn't configure next.config.ts security headers by default. CSP, HSTS, and X-Frame-Options are absent in most Cursor-generated Next.js apps.
Open Database Rules
Cursor-generated Supabase setup frequently skips RLS policies. AI models reproduce common patterns from training data — which includes many insecure configurations.
Exposed AI Endpoints
Cursor AI chat features often generate `/api/chat` routes without auth checks. Anyone can call your OpenAI proxy endpoint and use your API quota.
The Cursor + SecuriSky workflow
Build with Cursor
Use Cursor Agent as you normally would — build fast, ship your MVP, get live users.
Scan with SecuriSky
Paste your deployed URL. SecuriSky runs 27 checks in 60 seconds across security, UX, SEO, accessibility, and CRO.
Review prioritized findings
Critical issues first. Each finding includes the exact evidence and confidence level (confirmed/possible).
Paste fix prompts into Cursor
Copy the AI fix prompt → open Cursor Agent → paste and run. Most critical security fixes are one prompt away.
What a first scan of a Cursor-built app typically finds
- Stripe secret key in NEXT_PUBLIC_ variable — visible in browser console
- Supabase RLS disabled — unauthenticated API call returns all user records
- Missing Content-Security-Policy in next.config.ts
- AI chat route /api/chat accepts requests without authentication
- No rate limiting on /api/auth/login — brute force possible
Common questions
Cursor generated my code — why would it have security issues?
Cursor is excellent at writing functional code fast, but it optimizes for "does it work" not "is it secure". It draws from training data that includes many examples without security headers, without RLS policies, and with environment variables in client components. It also can't see your deployed infrastructure — it doesn't know your Supabase table has RLS disabled at the database level.
Can I paste SecuriSky findings back into Cursor Agent?
Yes — that's exactly the workflow SecuriSky is designed for. Every finding includes a ready-to-paste Cursor Agent prompt that describes the issue, shows the affected file, and asks Cursor to apply the specific fix. Most security issues can be resolved in a single Cursor Agent turn.
I'm using Cursor with Claude 3.5 Sonnet / GPT-4o. Are results different?
The security gaps are consistent regardless of which model you use inside Cursor — they're deployment-time issues (missing headers, open database rules, exposed secrets) not code-quality issues. SecuriSky scans your live deployed app, not the model that generated it.
Does SecuriSky work for Electron apps or CLI tools built with Cursor?
SecuriSky scans web applications accessible via a public URL. It's designed for deployed SaaS, web apps, and APIs — not desktop applications, CLI tools, or internal tools without a public endpoint.
My app is still in development on localhost — can I scan it?
Not directly — SecuriSky needs a publicly accessible URL. You can use ngrok or similar tools to temporarily expose localhost for scanning, or wait until you have a staging/preview deployment on Vercel or Netlify.
