Advisory

Source description from Wordfence Intelligence, credited to Abdi Pranata.

The Sirv plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the sirv_disconnect function hooked via AJAX in versions up to, and including, 7.1.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to disconnect the sites serv account.
