Summary

The Jane Menu WordPress plugin before 1.5.1 has a missing capability and nonce check on one of its form handlers that unauthenticated users can reach, letting them bind any published page to a remote document of their choosing. The plugin then outputs that document's head and body into the page without escaping (CWE-79), so an unauthenticated attacker can run arbitrary JavaScript in the browser of any visitor to that page, including an administrator.
