Mementor Core <= 2.2.5 - Authenticated (Subscriber+) Privilege Escalation

The Mementor Core plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.2.5. This is due to plugin not properly handling the user switch back function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges by accessing an administrator account through the switch back functionality.
