Can v0.dev components have XSS vulnerabilities?

React, which v0.dev generates code for, provides built-in XSS protection by escaping values embedded in JSX by default. However, v0-generated code can still introduce XSS risks if it uses dangerouslySetInnerHTML, constructs URLs from user input without sanitization, or renders user-provided content in attributes like href or src. Components that display dynamic content from APIs or databases are particularly at risk if the data source is compromised. Server-side rendering can also introduce XSS if proper escaping is not applied during hydration. UNPWNED checks XSS-relevant browser controls such as CSP. Reflected-XSS probes are not enabled in the current production profile, and stored XSS requires code review or targeted manual testing.
