How to fix?

There is no fixed version for Echo:latest packagekit.

NVD Description

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

A flaw was found in PackageKit. PackageKit skips the polkit authorization check for transactions carrying the SIMULATE (dry-run) flag. In the dnf5 backend, the RepoRemove handler ignores that contract and always executes the real transaction because its guard is written as (role == REPO_REMOVE || !SIMULATE), which is always true for RepoRemove. An unprivileged local user can therefore perform a genuine package uninstall while claiming to simulate. This vulnerability only affects systems using PackageKit with the dnf5 backend.
