{"id":"CVE-2026-85097","published":"2026-10-08T07:16:31.710","lastModified":"2026-10-08T17:24:11.230","description":"The Bricksforge plugin for WordPress is vulnerable to unauthenticated arbitrary file upload in versions up to, and including, 3.1.8.9. 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.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://bricksforge.io/version-changelog/","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e993c929-f175-43a7-92e6-9d3b089b8dde?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The Bricksforge plugin for WordPress allows unauthenticated attackers to upload and execute arbitrary PHP code by exploiting insufficient validation of the 'temporaryFileUploads' parameter.","exploitability":"Exploitation is moderately hard as it requires obtaining a valid nonce and crafting a specific file upload, but the lack of a patch means the vulnerability remains active.","blast_radius":"If exploited, this vulnerability could result in full server compromise, allowing attackers to execute arbitrary code and potentially gain control over the affected WordPress site.","remediation":"Upgrade to Bricksforge version 3.1.8.10 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","upload","php"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-08T08:40:54.786Z"}}
