description

Jetty HttpClient can disclose forward-proxy credentials to a destination server. This occurs when requests use a forward proxy and the destination server responds with a proxy-authentication status.

mitigation

Until a fixed release is identified, avoid configuring forward-proxy credentials for affected Jetty HttpClient requests and restrict outbound requests to trusted destinations. No fixed version is recorded for org.eclipse.jetty:jetty-client.
