Unauthenticated Payment Replay in Clover Payment Gateway for WooCommerce

Publication date: 2026-07-27

Last updated on: 2026-07-27

Assigner: WPScan

Description
The Clover Payment Gateway by Zaytech for WooCommerce WordPress plugin before 1.3.6 does not verify that an approved external payment record actually belongs to the WooCommerce order being completed, nor that the paid amount matches the order total, allowing unauthenticated users to mark arbitrary orders as paid by replaying a single genuinely-approved payment reference (for example one obtained from their own minimal purchase).

Executive Summary

This vulnerability affects the Clover Payment Gateway plugin for WooCommerce before version 1.3.6. It allows unauthenticated users to mark orders as paid by replaying a single legitimate payment reference, without verifying if the payment belongs to the correct order or matches the order total.

Detection Guidance

Check the installed version of the Clover Payment Gateway plugin in your WordPress admin panel. If the version is below 1.3.6, the system is vulnerable. Review payment logs for unauthorized order status changes marked as paid without corresponding transactions.

Impact Analysis

An attacker could exploit this to trick the system into accepting payments for orders they did not make. This could lead to financial losses, unauthorized order confirmations, and potential misuse of the payment system.

Compliance Impact

This vulnerability could violate compliance requirements by allowing unauthorized transactions, potentially breaching data integrity and financial transaction security standards required by regulations like GDPR and HIPAA.

Mitigation Strategies

Update the Clover Payment Gateway plugin to version 1.3.6 or later immediately. Disable the plugin temporarily if an update is not immediately available. Monitor order statuses and payment logs for suspicious activity.
