Summary

The SUMIT Payment Gateway for WooCommerce before version 4.0.0 does not verify that payment notifications from the payment provider are genuine before marking orders as paid. This allows unauthenticated users to mark pending orders as paid without completing payment.

Risk Assessment

Attackers can falsely mark orders as paid, leading to revenue loss and transaction integrity issues.

Recommendation

Update the plugin to version 4.0.0 or later, which includes the verification fix.
