Description
The PAYONE WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the credit card gateway settings in all versions up to, and including, 2.11.0. This is due to field style, type, size and iframe dimension settings being interpolated into inline JavaScript on the classic checkout page without escaping. This makes it possible for authenticated attackers with Shop Manager-level access or higher, who lack the unfiltered_html capability, to inject arbitrary web scripts that execute whenever a user visits the checkout page.
