Descriptions

The User Registration WordPress plugin before 3.0.4.2 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 User Registration de WordPress anterior a 3.0.4.2 no sanitiza ni escapa a algunas de sus configuraciones, lo que podría permitir a usuarios con altos privilegios, 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 User Registration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.0.4.1 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.
