Advisory
Source description from Wordfence Intelligence, credited to johska.
The Simple User Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 6.7 due to insufficient restriction on the 'profile_save_field' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wp_capabilities' parameter during a profile update.
