# CVE-2026-8719

> 8.8 HIGH

## Beschreibung

The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Privilege Escalation in version 3.4.9. This is due to missing WordPress capability enforcement in the MCP OAuth bearer-token authorization path, where any valid OAuth token causes MCP access to be granted without verifying administrator privileges. This makes it possible for authenticated (Subscriber+) attackers to invoke admin-level MCP tools and escalate privileges to Administrator.
