CVE-2026-8940

The WP Meta Sort Posts plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.9. This is due to missing or incorrect nonce validation on the top-level included script in msp-options.php. This makes it possible for unauthenticated attackers to change the plugin's msp_loop_file and msp_nav_location settings via a forged request 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 WP Meta Sort Posts para WordPress es vulnerable a falsificación de petición en sitios cruzados en todas las versiones hasta la 0.9, inclusive. Esto se debe a la validación de nonce faltante o incorrecta en el script incluido de nivel superior en msp-options.php. Esto hace posible que atacantes no autenticados cambien la configuración msp_loop_file y msp_nav_location del plugin mediante una petición falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace.
