WordPress Plugin Vulnerabilities
MStore API < 4.21.0 - Unauthenticated Payment Bypass via Multiple Payment Gateways
Description
The plugin does not verify the payment with the payment gateway before marking an order as paid on several of its payment-completion endpoints, allowing an unauthenticated attacker to mark an arbitrary order fully paid without paying and obtain goods or services for free.
