Description
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.
