CVE-2025-34085

critical

Description

An unrestricted file upload vulnerability in the WordPress Simple File List plugin prior to version 4.2.3 allows unauthenticated remote attackers to achieve remote code execution. The plugin's upload endpoint (ee-upload-engine.php) restricts file uploads based on extension, but lacks proper validation after file renaming. An attacker can first upload a PHP payload disguised as a .png file, then use the plugin’s ee-file-engine.php rename functionality to change the extension to .php. This bypasses upload restrictions and results in the uploaded payload being executable on the server.
