Scan your V0.dev app for vulnerabilities
V0.dev generates React components and UI code with AI. While primarily frontend, these components often handle user data and can introduce client-side security vulnerabilities.

Common vulnerabilities we find in V0.dev apps
These are the most frequent security issues discovered in V0.dev applications. VibeEval automatically tests for all of these and more.
Client-Side Data Exposure
Sensitive data rendered in HTML or stored in browser storage without proper protection.
XSS in Dynamic Content
AI-generated components may use dangerouslySetInnerHTML or fail to sanitize user input.
Exposed Environment Variables
Next.js apps may accidentally expose server-side env vars to the client.
Insecure Form Handling
Forms without CSRF protection or proper validation can be exploited.
Sensitive Data in URL Parameters
Passing tokens, IDs, or personal data in URLs where they can be logged or shared.
Missing Content Security Policy
Without CSP headers, the app is more vulnerable to XSS and code injection.

Frequently asked questions
Does VibeEval scan V0 component code directly?
VibeEval scans deployed applications. For component-level analysis during development, use our MCP integration.
What if I only use V0 for UI and have a separate backend?
VibeEval scans your entire deployed application including backend APIs. V0-specific issues are highlighted separately.
Can V0 components introduce security issues?
Yes, AI-generated UI code can have XSS vulnerabilities, insecure data handling, and other client-side security issues.
How do I secure a V0 + Vercel deployment?
Enable security headers in vercel.json, use environment variables properly, and scan with VibeEval before launch.
Test your V0.dev app before launch
Start testing your V0.dev application for security vulnerabilities before you go live.
