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.

Don’t ship with vulnerabilities

Most V0.dev apps have 3-5 security issues at launch. Find yours in under 2 minutes.
