CVE-2026-1404

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the filter parameters (e.g., 'filter_first_name') in all versions up to, and including, 2.11.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Summary		(es) El plugin Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin para WordPress es vulnerable a cross-site scripting reflejado a través de los parámetros de filtro (por ejemplo, 'filter_first_name') en todas las versiones hasta la 2.11.1, inclusive, debido a una sanitización de entrada y un escape de salida insuficientes. Esto permite a los atacantes no autenticados inyectar scripts web arbitrarios en páginas que se ejecutan si logran engañar a un usuario para que realice una acción como hacer clic en un enlace.
