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."}],"title":"Request a Quote for WooCommerce <= 2.9.2 - Unauthenticated Arbitrary File Upload via AJAX Popup Handler","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3417ec27-6abf-45c7-945f-6ef456ba1187?source=cve"},{"url":"https://woocommerce.com/products/request-a-quote-plugin-for-woocommerce/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"t4g0"}],"timeline":[{"time":"2026-09-25T17:47:32.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-18143","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-09-26T22:43:49.202450Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-26T22:51:17.345Z"}}]}}
