Name of the Vulnerable Software and Affected Versions
LWP::UserAgent versions prior to 6.83
Description
LWP::UserAgent leaks Authorization and Proxy-Authorization headers during cross-origin redirects. When a 3xx response is received, the redirect handler only removes the Host and Cookie headers before the subsequent request. Consequently, caller-supplied Authorization and Proxy-Authorization headers are transmitted unchanged to the redirect target, even if the scheme, host, or port changes. This allows a redirect to an attacker-controlled host to disclose the caller's credentials.
Recommendations
Update to version 6.83 or later.
