Is Cursor + Claude Code secure?
Your AI editor ships your code. Did it ship your secrets?
Code shipped from Cursor or Claude Code is as secure as your prompts demanded — which usually means gaps. The recurring issues: committed secrets, SQL built by string interpolation, missing CSRF, and tutorial-grade CORS. Scan the deployed app after every shipping session; it takes 30 seconds.
Cursor, Claude Code, and Windsurf are the modern shipping pipelines. The same speed that makes them magical also makes them dangerous. AI assistants will happily commit `.env` files, log API keys to console, and write SQL string-interpolation that begs to be injected. Run CheckVibe after every shipping session.

Why Cursor + Claude Code apps are commonly at risk
- AI-generated code follows the prompt, not security best practices — if you didn't mention CSRF, you didn't get CSRF.
- Secrets get committed when the AI generates `.env.example` and accidentally fills in real values.
- AI-suggested SQL frequently uses string interpolation rather than parameterized queries.
- AI tends to copy permissive CORS, debug logging, and "TODO: remove in prod" patches from training data.
- AI assistants don't check existing security headers or fix them unless asked.
Top security risks in Cursor + Claude Code apps
Committed secrets in git history
highAI editors will sometimes echo your `.env` into a commit message or sample file. CheckVibe scans your live site for any of 30+ key shapes the AI may have leaked.
SQL injection via string interpolation
highAI generates code that "looks fine" but interpolates user input into raw SQL. CheckVibe probes for it.
Verbose error logs in production
medium`console.log(error)` patterns common in AI-generated code leak stack traces to users.
Auth flows missing CSRF tokens
mediumAI-built forms frequently skip CSRF unless explicitly requested.
Permissive CORS copied from tutorials
medium`Access-Control-Allow-Origin: *` is in the training data; AI uses it by default.
How to fix Cursor + Claude Code security gaps
Use AI security prompts in your editor
CheckVibe outputs ready-to-paste prompts ("Add CSRF to this route") tuned for Cursor and Claude Code.
Wire CheckVibe to git hooks
Run `npx checkvibe` post-commit so secret leaks fail loudly.
Always specify "use parameterized queries" in your prompts
AI follows leads — give it the lead.
Audit `.env.example` before each commit
AI sometimes leaks actual values into example files.
How do you make a Cursor + Claude Code app rank in Google and AI search?
Securing the app is half the job, the other half is making it visible. AI engines (ChatGPT, Claude, Perplexity) only cite what their crawlers can read.
Tell your AI editor to make the site machine-readable
AI editors follow the prompt — and almost nobody prompts for AEO. Ask Cursor or Claude Code explicitly: "add generateMetadata to every route, create app/robots.ts allowing GPTBot/ClaudeBot/PerplexityBot, generate sitemap.ts and public/llms.txt." You'll get all four in one session.
Check what the crawler actually sees
If your editor scaffolded a client-only SPA (Vite, CRA), AI engines receive empty HTML. `curl -A "GPTBot" https://yourapp.com` shows the truth. If the body is empty, prerender or switch to SSR.
Add JSON-LD via one prompt
Organization + WebSite schema sitewide, FAQPage on Q&A pages, Article on posts. AI editors generate valid JSON-LD reliably when asked — validate with Google's Rich Results Test.
Make freshness visible
AI engines prefer dated, maintained content. Show "Updated [month year]" on key pages and keep dateModified in schema accurate.
Close the loop with an AEO scan
CheckVibe's visibility scan (68 SEO + 46 AEO checks) outputs findings as paste-ready fix prompts for Cursor and Claude Code — scan, paste, re-scan.

FAQ
Can AI editors leak my API keys?
Yes. They can include secrets in suggested code, in `.env.example`, or in commit messages. CheckVibe scans your live deployment for exposed keys.
Should I scan my app after every Cursor session?
Every meaningful shipping session, yes. The fastest way is the MCP server — your editor can trigger the scan itself — or one curl to the REST API from CI.
How does CheckVibe complement my AI editor?
Your AI editor writes code. CheckVibe checks if it shipped safely. We also output AI-formatted fix prompts you can paste back into Cursor.
