Descriptions

The EventON WordPress plugin before 4.5.5, EventON WordPress plugin before 2.2.7 does not sanitize and escape some of its 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 EventON WordPress anterior a 4.5.5 y el complemento EventON WordPress anterior a 2.2.7 no sanitizan ni escapan a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, como el administrador, realizar ataques de cross site scripting almacenado incluso cuando la capacidad unfiltered_html no está permitida. (por ejemplo, en configuración multisitio).

The EventON plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.5.4 (premium) & 2.2.7 (free) 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.
