What is CVE-2026-1400?

The AI Engine, a chatbot and AI framework plugin for WordPress, is prone to an arbitrary file upload vulnerability due to insufficient validation of file types in the rest_helpers_update_media_metadata function. This flaw permits authenticated users with Editor-level access and higher to upload potentially harmful files onto the server. An attacker could upload a harmless image and later exploit the update_media_metadata endpoint to rename the file to a PHP executable, leading to the execution of malicious code in the site's uploads directory.

Affected Version(s)
