NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup2-devel package and not the libsoup2-devel package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

A flaw was found in libsoup. After a CONNECT tunnel is established through an HTTP proxy, libsoup incorrectly attaches the Proxy-Authorization header to subsequent HTTPS requests sent through that tunnel to the destination server. This allows the destination server to capture proxy credentials, leading to information disclosure.
