This makes it possible for unauthenticated attackers to write a .php file to a web-served, PHP-executing location and, by supplying their own Google Drive file and OAuth token as the content source, execute arbitrary code on the server. The required save-design nonce is handed to anonymous callers by the nbd_check_use_logged_in endpoint, so it presents no barrier.","published":"2026-10-14T02:17:01.720","modified":"2026-10-14T18:19:35.843","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3716244/printcart-integration/trunk/includes/class.nbdesigner.php"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3716244%40printcart-integration%2Ftags%2F2.9.2&old=3715643%40printcart-integration%2Ftags%2F2.9.1"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/788461ba-2cf2-49d2-bbaa-a02de15f33ae?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-14T18:19:35.843"}}
