Paid Member Subscriptions <= 3.0.7 - Missing Authorization to Authenticated (Subscriber+) Cross-User Subscription Hijack
The Paid Member Subscriptions plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 3.0.7. This is due to missing ownership validation on the pms_current_subscription POST parameter in the process_checkout function, allowing any authenticated user to reference subscriptions belonging to other users. This makes it possible for authenticated attackers, with subscriber-level access and above, to hijack another user's subscription by supplying an arbitrary subscription ID during checkout, modifying or taking over subscriptions belonging to other members.
