CVE-2026-1165

The Popup Box plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.1.1. This is due to a flawed nonce implementation in the 'publish_unpublish_popupbox' function that verifies a self-created nonce rather than one submitted in the request. This makes it possible for unauthenticated attackers to change the publish status of popups via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.

Summary		(es) El plugin Popup Box para WordPress es vulnerable a la falsificación de petición en sitios cruzados en todas las versiones hasta la 6.1.1, inclusive. Esto se debe a una implementación de nonce defectuosa en la función 'publish_unpublish_popupbox' que verifica un nonce autocreado en lugar de uno enviado en la petición. Esto hace posible que atacantes no autenticados cambien el estado de publicación de los popups a través de una petición falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace.
