The Directory Listings WordPress plugin – uListing plugin for WordPress is vulnerable to unauthorized modification of data and PHP Object Injection due to a missing capability check on the stm_listing_ajax AJAX action in all versions up to, and including, 2.2.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to update post meta data and inject PHP Objects that may be unserialized. A capability check was added in 2.1.8, but the unserialize is still present.
