Overview
Affected versions of this package are vulnerable to URL Redirection to Untrusted Site ('Open Redirect') via the normalization process of the HTTP Location header due to improper input parsing in the _make_location_absolute
function.
An attacker can redirect users to an attacker-controlled website by manipulating the URL input that lacks a scheme but starts with //
, which leads the server to treat the subsequent string as the hostname, replacing the original intended destination.
