Descriptions

The HTML Forms WordPress plugin before 1.3.33 does not sanitize and escape the form message inputs, allowing high-privilege users, such as administrators, to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disabled.

El complemento de WordPress HTML Forms anterior a 1.3.33 no sanitiza ni escapa las entradas de mensajes del formulario, lo que permite a usuarios con altos privilegios, como administradores, realizar ataques de Cross Site Scripting almacenado (XSS) incluso cuando la capacidad unfiltered_html está deshabilitada.

The HTML Forms – Simple WordPress Forms Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.3.32 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.
