CVE-2026-1075

The ZT Captcha plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.4. This is due to improper nonce validation on the save_ztcpt_captcha_settings action where the nonce check can be bypassed by sending an empty token value. This makes it possible for unauthenticated attackers to modify the plugin's 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 ZT Captcha para WordPress es vulnerable a la falsificación de petición en sitios cruzados en todas las versiones hasta la 1.0.4, inclusive. Esto se debe a una validación de nonce incorrecta en la acción save_ztcpt_captcha_settings, donde la comprobación de nonce puede ser eludida enviando un valor de token vacío. Esto hace posible que atacantes no autenticados modifiquen 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.
