CVE-2026-14183
The Classified Listing WordPress plugin before 5.3.9 does not verify that the order targeted by its payment-receipt handler belongs to the requesting user, allowing authenticated users with subscriber-level access to read the payment receipt details of any other user's order.
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.
