Advisory

Source description from Wordfence Intelligence, credited to Ananda Dhakal.

The WSP MCP – WordPress MCP – Connect Claude, codex, antigravity or any other AI Agent plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 2.7.0. This is due to missing object-level capability checks on caller-supplied post IDs in write ability callbacks, allowing Contributors to act on content they do not own or lack permission to modify. This makes it possible for authenticated attackers, with contributor-level access and above, to modify or delete posts, pages, and media items owned by higher-privileged users, including publishing content beyond their role's capabilities.
