Advisory

Source description from Wordfence Intelligence, credited to István Márton.

The WP Remote Users Sync plugin for WordPress is vulnerable to unauthorized access of data and addition of data due to a missing capability check on the 'refresh_logs_async' functions in versions up to, and including, 1.2.11. This makes it possible for authenticated attackers with subscriber privileges or above, to view logs.
