CVE-2018-20060 2 Fedoraproject, Python 2 Fedora, Urllib3 2021-06-15 5.0 MEDIUM 9.8 CRITICAL
urllib3 before version 1.23 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.
