{"id":"CVE-2026-18143","state":"PUBLISHED","title":"Request a Quote for WooCommerce <= 2.9.2 - Unauthenticated Arbitrary File Upload via AJAX Popup Handler","description":"The Request a Quote for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.9.2 via the `afrfq_submit_quote_via_popup()` function. 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.","publishedAt":"2026-09-26T06:39:44.226Z","updatedAt":"2026-09-26T22:51:17.345Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["Addify Request a Quote for WooCommerce"],"affected":[{"vendor":"Addify","product":"Request a Quote for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.9.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3417ec27-6abf-45c7-945f-6ef456ba1187?source=cve","https://woocommerce.com/products/request-a-quote-plugin-for-woocommerce/"],"weaknesses":["CWE-434"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/18xxx/CVE-2026-18143.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-18143","state":"PUBLISHED","datePublished":"2026-09-26T06:39:44.226Z","dateUpdated":"2026-09-26T22:51:17.345Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-28T18:54:42.563Z"},"containers":{"cna":{"title":"Request a Quote for WooCommerce <= 2.9.2 - Unauthenticated Arbitrary File Upload via AJAX Popup Handler","descriptions":[{"lang":"en","value":"The Request a Quote for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.9.2 via the `afrfq_submit_quote_via_popup()` function.
