Descriptions

The Tutor LMS WordPress plugin before 2.0.10 does not escape some course parameters, 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 plugin Tutor LMS de WordPress versiones anteriores a 2.0.10, no escapa a algunos parámetros del curso, lo que podría permitir a usuarios con altos privilegios, como el administrador, llevar a cabo ataques de tipo Cross-Site Scripting Almacenado, incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en la configuración multisitio)

The Tutor LMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the topic name and lesson name parameters in versions up to, and including, 2.0.9 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.
