View online: https://www.drupal.org/sa-contrib-2026-058 Project: Commerce Realex / Global Payments [1] Date: 2026-June-24 Security risk: *Moderately critical* 12 ∕ 25 AC:Basic/A:None/CI:None/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Access Bypass Affected versions: <3.0.2 CVE IDs: CVE-2026-13238 Description:  This module enables you to take payments through the Global Payments / Realex Hosted Payment Page (HPP), either via a lightbox iframe or via a full-page redirect. When the gateway is configured with the *redirect* payment method, the module doesn't sufficiently verify the authenticity of the payment response returned by Global Payments. The *lightbox* payment method validates the signature and is not affected, so sites that use the lightbox payment method are not affected. Solution:  Install the latest version: * If you use the commerce_realex module <=3.0.1, upgrade to commerce_realex 3.0.2 [3]. The redirect payment response is now cryptographically verified against the merchant shared secret . Sites that cannot update immediately should disable this payment gateway, until the update can be applied.
