Advisory
Source description from Wordfence Intelligence, credited to Jerome Bruandet.
The MStore API plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.1.5. This is due to unrestricted access to the 'register' and 'update_user_profile' routes. This makes it possible for unauthenticated attackers to create new administrator accounts, delete existing administrator accounts, or escalate privileges on any account.
