Vulnerability from drupal

Published

Modified

2026-08-26 17:35

Summary

Details

This module integrates Drupal Commerce with the CyberSource payment gateway.

The module does not correctly verify the integrity of data returned by the payment provider. A timing attack could allow an attacker to trick the site into registering that payment has been received even if it hasn't.

This issue only affects the Secure Acceptance Hosted Checkout gateway integration.
