The vulnerabilities described here align with the OWASP Top 10, the industry-standard list of the most critical web security risks, and MITRE CWE Top 25. Severity uses CVSS v3 scoring from NIST's National Vulnerability Database.
Platform-aware security audit for apps built with Windsurf. What it covers, what it finds, and how to run one in 30 seconds.
A Windsurf security audit covers four dimensions. They are the same four we check on every app, no matter how it was built. For Windsurf apps, Security and Reliability are where the worst findings show up.
Every AI code builder has its own output patterns — consistent ways it structures routes, handles environment variables, sets up middleware, and manages errors. Our scanner is calibrated to Windsurf's patterns. That means faster detection and fewer false positives.
These are not flaws in Windsurf. They are standard hardening steps that no code generator does for you. All are simple to fix once found.

Three things to check before your Windsurf app goes live:
# 1. Search your build output for exposed secrets # Look for these patterns in your browser bundle: grep -r "OPENAI_API_KEY\|sk-\|stripe_secret\|service_role" ./dist # 2. Test rate limiting manually # Hit your /api/login endpoint 20 times in 10 seconds # If it accepts all 20 — you have no rate limiting # 3. Trigger a 500 error # Call an endpoint with bad input # If the response includes a stack trace — fix your error middleware
This list covers the six most common critical and high findings. An LRC scan checks all of these plus 40+ additional vectors across reliability, performance, and monitoring. For the full step-by-step hardening walkthrough, see our guide to securing a Windsurf app.

Scan my Windsurf app — freeNo. Windsurf is a well-built tool that produces high-quality code. The gaps come from configuration defaults and the limits of any code generator. Rate limiting, header middleware, secret handling, and monitoring all need decisions specific to your deployment. These are standard hardening steps.
The six most common issues are all fixable in under 2 hours total: rate limiting middleware (20–30 min), environment variable audit and rotation (20 min), error middleware (15 min), HTTP headers (10 min), CSRF middleware (10 min), error tracking setup (10 min). The scan tells you exactly what to fix. Our Code Care DFY Technical Setup ($1,999 setup fee + $2,999/mo) implements all of it for you.
No. The LRC scanner is URL-based — it tests what is publicly exposed from your live app, which is where real attackers start. No GitHub access, no source code, no deployment credentials required.
The four dimensions and methodology are the same. The platform-specific checks differ — each AI builder produces its own patterns in how it structures routes, handles environment variables, and sets up middleware. See also: Lovable security audit · Claude Code security audit.

Windsurf is an AI-powered IDE built by Codeium. Lovable and Bolt run in the browser and build a whole app from a prompt. Windsurf is different: it works inside your local dev environment. Its AI coding agent, Cascade, reads your codebase, edits many files at once, runs commands, and builds new features from plain-English requests — the same agent-style workflow as Claude Code.
The security risks differ from browser-based builders too. Windsurf apps tend to have code-level issues, not platform-configuration gaps. Cascade writes database queries, API routes, and auth logic — and any of these can carry OWASP-class flaws if your prompt never asked for security constraints.
The Windsurf-specific patterns we see most in audits: missing input validation on AI-generated API routes, N+1 query patterns from generated ORM code, and no rate limiting on endpoints the AI scaffolded quickly.
Run each check before going live. Every item here has caused a real production incident in AI-built apps.
| Check | Why it matters | How to verify |
|---|---|---|
| No secrets in code or git history | AI agents hardcode credentials during generation. Keys committed once stay in history even after deletion. | Run gitleaks on the full repo history before first push |
| All API routes require authentication | Windsurf scaffolds fast; auth middleware is often added to some routes, not all. | Test each route without a valid session token |
| Input validation on every user-facing endpoint | AI-generated handlers accept whatever arrives. SQL injection and XSS both start with unvalidated input. | Check validation on every POST/PUT route |
| Rate limiting on critical endpoints | No rate limit on login or signup invites credential stuffing. No limits on APIs invite abuse and surprise bills. | Use our free API rate-limit checker |
| HTTP security headers set | CSP, HSTS, and X-Frame-Options are absent by default on most frameworks Windsurf scaffolds. | Check with our free security headers scanner |
| Error tracking installed | Without error tracking, production errors are invisible until customers complain. | Verify error tracking fires on a thrown exception |
| Database access controls reviewed | ORM shortcuts can return rows a user should not see. Multi-tenant apps need explicit row ownership checks. | Audit every query that uses a user-supplied ID parameter |
The free scan checks the live-URL version of most of these — headers, rate limiting, exposed endpoints — in about 30 seconds. The $499 Launch Readiness Audit covers all four dimensions with line-level findings and a fix roadmap.

What does a security audit for Windsurf apps check?
It checks the three patterns we see most often: environment variables referenced in client-side code (where anyone can read them), API endpoints without rate limiting, and error responses that leak stack traces. Windsurf writes strong full-stack code fast. The security layer has to be added by hand.
Is my Windsurf app ready for production?
Check three things. No environment variables referenced in client-side code. Rate limiting on your API endpoints. Error responses that don't leak stack traces. Windsurf's speed doesn't cover these steps — a free scan at launchreadycode.com/free-scan checks all three on your live app in about a minute.
What should be on a Windsurf app security checklist?
Five checks: (1) no environment variables in client-side bundles, (2) rate limiting on all API endpoints, especially auth and payment, (3) error responses cleaned so stack traces never reach the client, (4) HTTP security headers set, (5) error tracking and uptime monitoring on before launch.
How do I secure an app I built with Windsurf?
Search your client-side code for environment variable references and move them server-side. Add rate limiting to your API endpoints. Clean up error responses so they return a generic message, not a stack trace. These three cover the patterns found most often in Windsurf-built apps.
Is Windsurf safe for production use?
Yes — after you add the security layer yourself. Windsurf writes strong full-stack code fast. It does not set up rate limiting, HTTP security headers, secret handling, or error sanitization for you. We most often find secrets referenced client-side, missing rate limiting, and stack traces leaking from error responses.
What security issues do apps built with Windsurf have?
Three issues come up again and again: environment variables referenced in client-side code (which makes them public), API endpoints with no rate limiting, and error responses that leak stack traces. All are configuration gaps. You can fix each one without touching the core app logic Windsurf generated.
