Technical details

The AI Engine plugin for WordPress (v3.4.9) contains a privilege escalation vulnerability due to improper authorization checks in the Model Context Protocol (MCP) OAuth bearer-token path. Specifically, the plugin fails to enforce WordPress capability checks when a valid OAuth token is presented, granting MCP access regardless of the user's actual role. An authenticated attacker with minimal (Subscriber+) privileges can exploit this to invoke admin-level MCP tools. This can be leveraged to escalate privileges to the Administrator role, leading to full site compromise. A changeset (3533527) indicates that a fix has been developed.
