DescriptionNVD

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.

AnalysisAI

Authenticated attackers can escalate privileges to Administrator in AI Engine WordPress plugin version 3.4.9 through improper authorization in the MCP OAuth bearer-token implementation. The plugin accepts any valid OAuth token for Model Context Protocol (MCP) access without verifying administrator privileges, allowing low-privileged users (Subscriber+) to execute admin-level MCP tools. …

RemediationAI

Within 24 hours: Audit WordPress sites running AI Engine v3.4.9 for active users and recent MCP OAuth token activity; disable the plugin if not critical to operations. Within 7 days: Contact AI Engine developers for patched version status and timeline; implement IP whitelisting or WAF rules to restrict MCP endpoints if the plugin cannot be removed. …
