### Impact A XSS vulnerability in the provided (outdated) Swagger-UI is exploitable in applications using lithium with Swagger-UI enabled. This allows an attacker gain Remote Code Execution (RCE) and potentially exfiltrate secrets in the context of this swagger session.

### Patches The used swagger-ui was updated by switching to the latest version of dropwizard-swagger in 8b9b406d608fe482ec0e7adf8705834bca92d7df

### Workarounds The risk of injected external content can be reduced by setting up a [Content-Security-Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy).
