Descriptions

The Newsletter WordPress plugin before 8.85 does not sanitise and escape some of its Form settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

El complemento Newsletter de WordPress anterior a la versión 8.85 no depura ni escapa de algunas de las configuraciones de formulario, lo que podría permitir a usuarios con privilegios elevados, como el administrador, realizar ataques de Cross Site Scripting Almacenado incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en una configuración de varios sitios).
