How do I security test a v0.dev project?
Deploy your v0-built application to staging and scan the live URL for missing headers, exposed endpoints, configuration issues, and leaked client-side secrets. Test authentication and authorization separately. UNPWNED's 721-check full suite spans 36 scanners after current ownership proof plus explicit active-testing authorization and generates a prioritized deterministic report.
