If you cannot patch yet, restrict user roles and permissions to limit who can perform subscription actions, and monitor for suspicious subscription cancellations. Avoid granting Subscriber+ roles to untrusted users. Review plugin updates regularly for a security patch addressing this issue.
Description
The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content WordPress plugin before 4.16.17 does not verify that the user performing a subscription action owns the targeted subscription, allowing any authenticated user (Subscriber+) to cancel other users' active subscriptions via an Insecure Direct Object Reference.
