CVE-2026-16594
The WP Directory Kit WordPress plugin before 1.5.5 does not perform authorization or nonce checks on one of its authenticated AJAX actions, allowing any authenticated user such as a Subscriber to disclose the WP Directory Kit WordPress plugin before 1.5.5 settings including sensitive API keys and secrets.
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.
