CVE-2018-20060

Advisory

Kubernetes 7.0.1, 8.0.1 and 9.0.0a1 include a fix for CVE-2018-20060: 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.
