Descriptions

The Customizr theme for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.3.0. This is due to missing or incorrect nonce validation on the czr_fn_post_fields_save() function. This makes it possible for unauthenticated attackers to post fields via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

El Customizr theme para WordPress es vulnerable a Cross-Site Request Forgery (CSRF) en versiones hasta la 4.3.0 incluida. Esto se debe a una validación nonce faltante o incorrecta en la función czr_fn_post_fields_save(). Esto hace posible que atacantes no autenticados publiquen campos a través de una solicitud falsificada, siempre que puedan engañar al administrador del sitio para que realice una acción como hacer click en un enlace.
