The EventON WordPress plugin before 2.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored HTML Injection attacks even when the unfiltered_html capability is disallowed.
El complemento EventON WordPress anterior a 2.2 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con privilegios elevados, como el administrador, realizar ataques de inyección de HTML almacenado incluso cuando la capacidad unfiltered_html no está permitida.
The EventON plugin for WordPress is vulnerable to HTML Injection via admin settings in all versions up to, and including, 2.1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary HTML 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.
