Summary
Exposure of Sensitive Information to an Unauthorized Actor in urllib3
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.
Severity
9.8 (Critical)

Summary
Exposure of Sensitive Information to an Unauthorized Actor in urllib3
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.
Severity
9.8 (Critical)
