The Ultimate WordPress Toolkit – WP Extended plugin for WordPress is vulnerable to Remote Code Execution in version 3.0.11. This is due to a missing capability check on the 'wpext_handle_snippet_update' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute code on the server providing an admin has created at least one code snippet.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
