How to fix?

Upgrade SLES:15.6 wcurl to version 8.22.0-150600.4.58.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wcurl package and not the wcurl package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

An HTTP proxy can trick libcurl into sending the origin's credentials (Basic password, or a Negotiate/Kerberos ticket) to the proxy itself, by answering the CONNECT tunnel request with 401 WWW-Authenticate: instead of the expected 407 Proxy-Authenticate:.
