    CVE-2018-20060

    Published: 11 Dec 2018Last Modified: 7 Aug 2026

    Summary:

    Details: 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.
