CVE-2026-3191

The Minify HTML plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.12. This is due to missing or incorrect nonce validation on the 'minify_html_menu_options' function. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Summary		(es) El plugin Minify HTML para WordPress es vulnerable a la falsificación de petición en sitios cruzados en todas las versiones hasta la 2.1.12, inclusive. Esto se debe a la validación de nonce ausente o incorrecta en la función 'minify_html_menu_options'. Esto hace posible que atacantes no autenticados actualicen la configuración del plugin 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.
