The MountDev AI MCP Connector for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.6.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to obtain an administrator-bound OAuth Bearer token via a self-registered client, granting full administrator-equivalent access to the plugin's MCP tool surface and all exposed WordPress content, users, and options. This is exploitable by combining the publicly accessible Dynamic Client Registration endpoint, which allows unauthenticated callers to register arbitrary OAuth clients with an attacker-controlled redirect_uri, with the unprotected authorization endpoint to complete the full OAuth flow without any administrator interaction.
