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, access tokens created as part of admin's impersonation of a user are not cleared at the end of impersonation which may lead to unnecessary sensitive info disclosure.
