Descriptions

The WP Database Backup WordPress plugin before 5.9 does not escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)

El plugin WP Database Backup de WordPress versiones anteriores a 5.9, no escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, como los administradores, llevar a cabo ataques de tipo Cross-Site Scripting Almacenado cuando la capacidad unfiltered_html no está permitida (por ejemplo, en una configuración multisitio)

The WP Database Backup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters in versions up to, and including, 5.8.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative 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.
