Security Advisory Description
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. (CVE-2018-20060)
Impact
For products with None in theVersions known to be vulnerable column, there is no impact.
This vulnerability may allow credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext.
