Several themes for WordPress are vulnerable to unauthorized modification of data due to a missing capability check on the activate_plugin() function called via an AJAX action in various versions. This makes it possible for authenticated attackers, with subscriber-level access and above, to activate arbitrary plugins.

Not sure which version you run? Run a passive check — it reads public files only.
