Advisory
Source description from Wordfence Intelligence, credited to Usama Arshad.
The Surfer plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.8.1.758. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for authenticated attackers, with contributor-level access and above, to elevate their privileges beyond those intended for their role.
