The Simple Membership WordPress plugin before 4.1.3 does not properly validate the membership_level parameter when editing a profile, allowing members to escalate to a higher membership level by using a crafted POST request.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
