The Square theme for WordPress is vulnerable to unauthorized plugin activation due to a missing capability check on the activate_plugin function called via an AJAX action in versions up to, and including, 2.0.0. This makes it possible for authenticated attackers , with subscriber-level access and above, to activate arbitrary plugins.
