Name of the Vulnerable Software and Affected Versions
MStore API versions prior to 4.21.0
Description
The MStore API WordPress plugin fails to verify payment status with the payment gateway before marking an order as paid on several payment-completion endpoints. This allows an unauthenticated attacker to mark an arbitrary order as fully paid without completing the actual payment, enabling the unauthorized acquisition of goods or services.
Recommendations
Update MStore API to version 4.21.0 or later.
