Description

The User Registration & Membership – Custom Registration Form Login Form and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 4.2.1 via the create_stripe_subscription() function due to missing validation on the ‘member_id’ user controlled key. This makes it possible for unauthenticated attackers to delete arbitrary user accounts that have registered through the plugin.
