## Description

The WP Abstracts plugin for WordPress is vulnerable to unauthorized modification of data via the reorder_topics AJAX action in all versions up to, and including, 2.7.6, due to a missing capability check on the wpabstracts_reorder_topics() function, which is protected only by a nonce that is given to front-end users. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change the display order of event topics.
