CVE-2021-32620
La Plataforma XWiki es una plataforma wiki genérica que ofrece servicios de ejecución para las aplicaciones construidas sobre ella. En las versiones anteriores a la 11.10.13, 12.6.7 y 12.10.2, un usuario deshabilitado en un wiki que utilizaba la verificación por correo electrónico para el registro podía volver a activarse utilizando el enlace de activación proporcionado para su registro. El problema ha sido parcheado en las siguientes versiones de XWiki: 11.10.13, 12.6.7, 12.10.2, 13.0. Es posible solucionar el problema restableciendo la propiedad `validkey` de los usuarios de XWiki deshabilitados. Esto se puede hacer editando el perfil del usuario con el editor de objetos
