v0.dev Security

v0.dev Security Scanner

Using v0.dev to generate UI components? Make sure the code it generates is secure. We check for common vulnerabilities in AI-generated React code.

v0.dev Security Considerations

v0.dev makes development fast, but AI-generated code often skips security best practices:

  • !Generated components may include insecure patterns
  • !XSS vulnerabilities in dynamic content handling
  • !Missing input validation and sanitization
  • !Insecure data fetching patterns

What We Check

XSS Prevention

Checks generated components for proper escaping and sanitization of user input and dynamic content.

Secret Detection

Scans for any API keys or secrets that may have been included in generated code examples.

Security Headers

Verifies your deployed app has proper security headers configured.

Auth Patterns

Reviews authentication and authorization patterns in generated code for common security issues.

What You'll Get

Security vulnerability report
XSS risk assessment
Secret exposure check
Security headers analysis
Code pattern review
Fix recommendations
AI-ready markdown export
Re-scan after fixes

Why v0.dev Apps Need Security Scanning

v0.dev by Vercel generates beautiful React components from natural language descriptions. While the generated code is functional and well-structured, AI-generated code can sometimes include patterns that introduce security vulnerabilities, especially when handling user input or fetching data.

When you integrate v0 components into a full application, security becomes your responsibility. The generated components need proper input validation, output encoding, and secure data handling practices. Without these safeguards, your application could be vulnerable to cross-site scripting (XSS), injection attacks, and data exposure.

VAS analyzes your deployed application to identify security issues in both v0-generated components and your custom code. We check for XSS vulnerabilities, insecure data handling, missing security headers, and exposed secrets.
