Descriptions

The Simple Basic Contact Form WordPress plugin before 20221201 does not sanitise 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 Simple Basic Contact Form de WordPress anterior a 20221201 no sanitiza ni escapa algunas de sus configuraciones, lo que podría permitir a usuarios con privilegios elevados, como el administrador, realizar ataques de Cross-Site Scripting (XSS) Almacenado incluso cuando la capacidad unfiltered_html no está permitida (por ejemplo, en una configuración multisitio).

The Simple Basic Contact Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several of its settings parameters in versions up to, and including, 20220207 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.
