How to fix?

Upgrade Debian:unstable gitlab to version 15.10.8+ds1-2 or higher.

NVD Description

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

In all versions of GitLab CE/EE since version 8.0, when an admin uses the impersonate feature twice and stops impersonating, the admin may be logged in as the second user they impersonated, which may lead to repudiation issues.
