Description

The MStore API WordPress plugin before 4.21.1 does not verify that the order targeted by its wallet payment handling belongs to the requester, and does not deduct the wallet balance for most payment methods, allowing any authenticated user, including Subscribers, to mark arbitrary orders as paid without any payment being taken.
