CVE-2026-16276
The Classified Listing WordPress plugin before 5.4.4 does not perform a capability check on an AJAX action that returns aggregated store revenue totals, allowing users with contributor-level access and above to read daily revenue figures normally restricted to administrators and report managers.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.
Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
