Description

A flaw was found in LWP::UserAgent, a component of perl-libwww-perl. This vulnerability allows a remote attacker to obtain a user's credentials by redirecting a request to an attacker-controlled host. When processing a redirect, the LWP::UserAgent fails to properly strip Authorization and Proxy-Authorization headers, leading to their unintended disclosure across different origins.
