How to fix?

There is no fixed version for Echo:latest cups.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cups package and not the cups package as distributed by Echo. See How to fix? for Echo:latest 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.
