CVE-2026-13329
The Buckaroo Woocommerce Payments Plugin WordPress plugin before 4.9.0 does not perform any capability check or nonce validation on an AJAX action that processes payment capture refunds, allowing any authenticated user, including Subscribers, to trigger refunds against captured orders.
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.
