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 scans v0-built applications for the full range of web vulnerabilities and provides prioritized findings with fix instructions.
