Executive Summary

The Synchrony Financing WordPress plugin before version 1.1.2 has an authorization flaw in a REST route that manages WooCommerce orders. This allows unauthenticated attackers to take over any order, change its details, and view the customer's personal data without needing to log in.

Detection Guidance

Check if the Synchrony Financing WordPress plugin version is between 1.0.5 and 1.1.1. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files for version details. Look for unauthorized order modifications in WooCommerce logs or database entries.

Impact Analysis

Unauthenticated attackers could take over your WooCommerce orders, modify them, and access customer personal data. This could lead to financial loss, data breaches, and reputational damage for businesses using the plugin.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection and access control. Organizations may face fines or legal consequences for non-compliance.

Mitigation Strategies

Update the Synchrony Financing plugin to version 1.1.2 or later immediately. Disable the plugin temporarily if an update is not immediately available. Review WooCommerce orders for unauthorized changes and restrict access to sensitive customer data.
