CVE-2026-5050 Details
Description
The Payment Gateway for Redsys & WooCommerce Lite plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in versions up to, and including, 7.0.0 due to successful_request() handlers calculating a local signature but not validating Ds_Signature from the request before accepting payment status across the Redsys, Bizum, and Google Pay gateway flows. This makes it possible for unauthenticated attackers to forge payment callback data and mark pending orders as paid when they know a valid order key and order amount, potentially allowing checkout completion and product or service fulfillment without a successful payment.
A vulnerability exists in the Payment Gateway for Redsys & WooCommerce Lite plugin for WordPress, in versions through 7.0.0. The issue arises from the successful_request() handlers, which calculate a local signature but fail to validate the Ds_Signature from incoming requests before updating payment status. This flaw is present in the Redsys, Bizum, and Google Pay gateway flows. As a result, unauthenticated attackers can forge payment callback data, marking pending orders as paid if they possess a valid order key and amount. This exploitation could lead to unauthorized completion of checkout processes and fulfillment of products or services without actual payment.
Users are advised to update the Payment Gateway for Redsys & WooCommerce Lite plugin to version 7.0.1 or a newer patched version.
