Summary

The Apache HttpClient prior to version 4.1.1 contains a vulnerability that reveals sensitive information to remote web servers. When used in conjunction with an authenticating proxy server, the HttpClient incorrectly sends the Proxy-Authorization header to the origin server. This behavior could allow attackers on the web server to log and capture the Proxy-Authorization header, leading to potential exposure of credentials or other sensitive data. It is crucial for users of affected versions to update to the latest release to mitigate this issue.
