The MagicForm plugin for WordPress is vulnerable to access and modification of data due to a missing capability check on the plugin's AJAX actions in all versions up to, and including, 1.6.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke those actions in order to delete or view logs, modify forms or modify plugin settings.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
