GHSA-H8C7-C2X8-J8GF

Vulnerability from github – Published: 2026-01-28 09:30 – Updated: 2026-01-28 09:30

Details

The AI Engine – The Chatbot and AI Framework for WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rest_helpers_update_media_metadata function in all versions up to, and including, 3.3.2. This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The attacker can upload a benign image file, then use the update_media_metadata endpoint to rename it to a PHP file, creating an executable PHP file in the uploads directory.

Severity ?

7.2 (High)
