CVE-2026-86850Network attack vector

Unauthenticated variation deletion via unchecked AJAX actions

Published Oct 9, 2026 · Updated Oct 9, 2026

Missing authorization in SKU Error Fixer for WooCommerce 1.0 and earlier allows remote attackers to delete variations via AJAX. Two AJAX actions accept unauthenticated requests without capability or nonce checks, exposing details of variations classified as obsolete and permanently deleting those variations. Exploitation requires reachable plugin AJAX actions and matching variation records; deletion leaves no recoverable copy within the plugin.
