Executive Summary

This vulnerability affects the WPForms WordPress plugin before version 2.0.2. It allows unauthenticated users to manipulate Stripe payment objects during form submissions without proper verification. Attackers can trigger full refunds or cancel subscriptions tied to payments created by other applications on the same Stripe account.

Detection Guidance

Check if your WPForms Lite plugin version is between 1.8.8.2 and 2.0.1.1. Review Stripe payment logs for unauthorized refunds or subscription cancellations. Look for suspicious form submissions that attempt to manipulate Stripe payment objects.

Impact Analysis

If you use WPForms Lite versions 1.8.8.2 through 2.0.1.1, an attacker could exploit this to refund payments or cancel subscriptions without authorization. This could lead to financial losses, disrupted services, or unauthorized refunds on your Stripe account.

Compliance Impact

This vulnerability could lead to unauthorized refunds or subscription cancellations, potentially violating data protection and financial compliance requirements under GDPR or HIPAA. Unauthorized transactions may result in non-compliance with financial transaction regulations.

Mitigation Strategies

Update WPForms Lite to version 2.0.2 or later immediately. Disable Stripe payment processing in WPForms if not in use. Monitor Stripe account activity for unauthorized transactions or refunds.
