This is due to insufficient validation of the attacker-controlled URL field in the 'temporaryFileUploads' parameter during form submission. An unauthenticated attacker can first obtain a valid nonce via the bricksforge_regenerate_nonce AJAX endpoint, then upload a GIF/PHP polyglot file to the temporary upload directory where MIME type validation is correctly performed. Subsequently, the attacker can submit a form with a crafted 'temporaryFileUploads' parameter where the server-side file path points to the validated GIF file, but the attacker-controlled url field ends with a .php extension. This makes it possible for unauthenticated attackers to upload and execute arbitrary PHP code on the server.","published":"2026-10-08T07:16:31.710","modified":"2026-10-08T07:16:31.710","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://bricksforge.io/version-changelog/"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e993c929-f175-43a7-92e6-9d3b089b8dde?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-08T07:16:31.710"}}
