Advisory
Source description from Wordfence Intelligence, credited to Jakub Herman.
Multiple plugins for WordPress are vulnerable to unauthenticated site takeover in various versions. This is due to a weak pseudo-random number generator that makes it possible for attackers to brute force and connect to the remote connection feature. This makes it possible for unauthenticated attackers to connect a site to their remote management software and take it over.
