Executive Summary

This vulnerability affects the Wallet System for WooCommerce plugin before version 2.7.10. It allows authenticated customers to enter an unvalidated wallet amount during checkout, which is not checked against their actual stored balance. This lets them reduce their order total, including to zero, and complete the purchase without paying the merchant.

Detection Guidance

Check the installed version of the Wallet System for WooCommerce plugin. If it is below 2.7.10, the system is vulnerable. Logs may show unusual checkout amounts or transactions completed with zero payment.

Impact Analysis

If you use the affected plugin, attackers could exploit this to pay less than the actual order total or pay nothing at all. This results in financial loss for merchants and undermines trust in the payment system.

Compliance Impact

This vulnerability could lead to financial losses for merchants, which may impact compliance with financial record-keeping requirements under regulations like GDPR (if payment data is mishandled) or HIPAA (if transactions involve protected health information). However, the primary issue is financial fraud rather than direct data exposure.

Mitigation Strategies

Update the Wallet System for WooCommerce plugin to version 2.7.10 or later immediately. Disable the plugin temporarily if an update is not available. Monitor transaction logs for suspicious activity.
