CVE-2026-85097

Bricksforge WordPress plugin unrestricted file upload

9.8 CRITICALEPSS 0.31%
  1. Published8 Oct 2026

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.
