Advisory
Source description from Wordfence Intelligence, credited to Jakub Herman.
The All In One Login plugin for WordPress is vulnerable to Privilege Escalation in versions 2.4.0 through 2.4.1. This is due to insufficient restriction on OTP login attempts. This makes it possible for unauthenticated attackers to brute force access to other users accounts, including administrators.
