Executive Summary

This vulnerability affects the Easy PayPal & Stripe Buy Now Button WordPress plugin. It allows unauthenticated attackers to set an arbitrary lower price for a purchase by manipulating a client-supplied field that determines the payment amount. The plugin fails to validate or derive the price on the server side, enabling price manipulation.

Detection Guidance

Check the installed version of the Easy PayPal & Stripe Buy Now Button plugin in your WordPress admin panel. If the version is between 1.8 and 2.0.5, the system is vulnerable. Compare the version against the latest release 2.0.6 or higher.

Impact Analysis

If you use the affected plugin versions (1.8 to 2.0.5), an attacker could purchase items at a lower price than intended, leading to financial losses. Since no authentication is required, anyone can exploit this vulnerability remotely.

Compliance Impact

This vulnerability could lead to unauthorized price manipulation during transactions, potentially violating financial transaction integrity requirements under GDPR and HIPAA. It may also undermine data protection measures if payment data is improperly handled due to incorrect pricing logic.

Mitigation Strategies

Update the plugin to version 2.0.6 or later immediately. If updating is not possible, consider disabling the plugin temporarily until an update is applied. Monitor network traffic for unusual payment requests with manipulated amounts.
