This is due to a logic flaw in the 'validate_cart_data' function. This makes it possible for unauthenticated attackers to bypass required paid addons and complete purchases at the base product price only, effectively stealing products by paying a fraction of the intended total. The vulnerability was partially patched in version 1.6.19.","published":"2026-08-22T14:16:32.807","modified":"2026-08-22T14:16:32.807","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/advanced-product-fields-for-woocommerce/trunk/includes/controllers/class-product-controller.php#L130"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3477476/"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3483410/"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5d9c1c3d-6882-4425-8d32-bdb57b4f133d?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T14:16:32.807"}}
