Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.13.1. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for unauthenticated attackers to elevate their privileges beyond those intended for their role.
