This is due to missing file extension and MIME type validation in the popup upload handler, which uses the raw attacker-supplied filename directly as the destination for `move_uploaded_file()`. This makes it possible for unauthenticated attackers to upload executable files, such as PHP files, to a web-accessible temporary RFQ upload directory when a public quote rule with the multi-page popup flow is enabled.","published":"2026-09-26T07:17:02.017","modified":"2026-09-26T07:17:02.017","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://woocommerce.com/products/request-a-quote-plugin-for-woocommerce/"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3417ec27-6abf-45c7-945f-6ef456ba1187?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-26T07:17:02.017"}}
