Summary

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.

Exploit prediction (EPSS)

4.49% probability of exploitation in the next 30 days, higher than 92% of all scored CVEs.
