CVE-2026-1399

The WP Google Ad Manager Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Summary		(es) El plugin WP Google Ad Manager Plugin para WordPress es vulnerable a cross-site scripting almacenado a través de la configuración de administrador en todas las versiones hasta la 1.1.0, inclusive, debido a una sanitización de entrada y un escape de salida insuficientes. Esto permite que atacantes autenticados, con permisos de nivel de administrador y superiores, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. Esto solo afecta a las instalaciones multisitio y a las instalaciones donde se ha deshabilitado unfiltered_html.
