Description SMASH SMASH 2023-10-16 10:09:02 UTC 
urllib3 before 1.24.2 does not remove the authorization HTTP header when
following a cross-origin redirect (i.e., a redirect that differs in host, port,
or scheme). This can allow for credentials in the authorization header to be
exposed to unintended hosts or transmitted in cleartext. NOTE: this issue exists
because of an incomplete fix for CVE-2018-20060 (which was case-sensitive).
