CVE-2026-107745
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to limited media file deletion due to insufficient file path validation in the uploadfile function in all versions up to, and including, 3.8.4 This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary media files on the server. This requires the administrator to have enabled the Public API option, and exploitation depends on the hourly cleanupfiles task running after the malicious upload.
