Descriptions

The Easy Forms for Mailchimp WordPress plugin through 6.8.10 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed

El complemento de WordPress Easy Forms para Mailchimp hasta la versión 6.8.10 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, como el administrador, realizar ataques de cross site scripting incluso cuando unfiltered_html no está permitido.

The Easy Forms for Mailchimp plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 6.8.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
