"urllib3 is a user-friendly HTTP client library for Python. When using urllib3's proxy support with 'ProxyManager', the 
'Proxy-Authorization' header is only sent to the configured proxy, as expected. However, when sending HTTP requests 
without using urllib3's proxy support, it's possible to accidentally configure the 'Proxy-Authorization' header even 
though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, 
urllib3 doesn't treat the 'Proxy-Authorization' HTTP header as one carrying authentication material and thus doesn't 
strip the header on cross-origin redirects. 

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
