Advisory
Source description from Wordfence Intelligence, credited to Khaled Alenazi.
The MemberHero – Simple User Registration & Login plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.9. 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.
