Description

The AI Engine plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the 'Meow_MWAI_Labs_MCP::can_access_mcp' function in versions 2.8.0 to 2.8.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to have full access to the MCP and run various commands like 'wp_create_user', 'wp_update_user' and 'wp_update_option', which can be used for privilege escalation, and 'wp_update_post', 'wp_delete_post', 'wp_update_comment' and 'wp_delete_comment', which can be used to edit and delete posts and comments.

Affected products

• AI Engine: from 2.8.0 before 2.8.4 — fixed in 2.8.4

How to fix

Upgrade to a fixed version: AI Engine 2.8.4. Check the vendor advisory for mitigations.
