Summary
The User Registration & Membership WordPress plugin before 5.2.0 does not enforce payment completion before activating a paid membership subscription, allowing unauthenticated users (after self-registering an account through the open registration flow) to obtain an active subscription on any paid plan without paying and access the gated content.
