Technical description

The User Registration & Membership WordPress plugin before 5.2.2 does not perform an authorization check on a membership-upgrade action and derives the user to modify from a caller-supplied identifier instead of the current user, allowing any authenticated user such as a subscriber to change another user's WordPress role and membership tier.
