How to fix?

There is no fixed version for Debian:14 cups.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cups package and not the cups package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.
