How do I security test a v0.dev project?

Deploy your v0-built application to a staging environment and run automated security scans against the live URL to detect missing headers, exposed endpoints, and configuration issues. Test all forms and API routes for injection vulnerabilities by submitting malicious payloads through each input field. Verify that authentication and authorization are enforced on every protected route by attempting to access resources without valid credentials. Check that sensitive data like API keys and database connection strings are not exposed in client-side JavaScript bundles. UNPWNED automates all of these checks with 700+ security checks across 40 scanners and generates a prioritized report with specific fixes for your v0-built application.
