Can apps built with v0.dev be hacked?

Applications built with v0-generated code can be hacked if security measures are not added beyond the generated UI components. v0 creates frontend code that handles presentation logic but does not implement authentication, authorization, rate limiting, or secure data handling. Attackers can target missing server-side validation, insecure API endpoints, broken access controls, and exposed sensitive data in client-side code. The risk is amplified when developers deploy v0-generated code directly without security review, treating it as production-ready. UNPWNED assesses externally observable header, exposure, endpoint, dependency, form, CORS, rate-limit, and error-disclosure signals. Paid reports add prioritized remediation guidance; internal authentication, authorization, validation, and data handling require direct review.
