The Tutor LMS WordPress plugin before 2.3.0 does not sanitise and escape some of its settings, which could allow users such as subscriber to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
El complemento Tutor LMS de WordPress anterior a 2.3.0 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios como suscriptores realizar ataques de Cross-Site Scripting almacenados incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en configuración multisitio).
The Tutor LMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.2.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with subscriber access to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
