AI UI component generator by Vercel
v0 generates React UI components from prompts. Since it focuses on frontend code, the security risks are primarily client-side — XSS via dangerouslySetInnerHTML, exposed API keys in component props, and lack of input sanitization in generated forms.
v0 sometimes uses dangerouslySetInnerHTML to render dynamic content without sanitization.
Replace with proper React rendering or use DOMPurify to sanitize HTML before rendering.
Generated components may accept API keys as props, exposing them in the client bundle.
Never pass secret keys as props. Use server-side API routes to proxy requests.
Generated forms lack client-side and server-side validation.
Add Zod or yup validation schemas. Validate on both client and server.
Generated fetch calls may not handle errors or validate response data properly.
Add try/catch blocks, validate response schemas, and handle network errors gracefully.
Admin UI components may render regardless of user role, leaking sensitive UI elements.
Implement proper role-based access control. Check permissions before rendering admin components.
v0 generates UI only — always add your own auth, validation, and error handling.
Copy generated components to your project and review before using in production.
Use Erzo to scan the final deployed app, not just the generated components.
