CVE-2026-12684
The Customer Reviews for WooCommerce WordPress plugin before 5.113.0 does not perform authentication, capability, or nonce checks on one of its media upload AJAX actions when the review media attachment feature is enabled, allowing unauthenticated users to upload media files (bounded to an image and video allowlist) to the Media Library and create attachment posts, leading to media library pollution and disk space exhaustion.
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.
