How to fix?

Upgrade Debian:unstable libsoup3 to version 3.6.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup3 package and not the libsoup3 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued the redirect.
