      "value": "Incus is a system container and virtual machine manager. Prior to version 7.2.0, missing authorization checks exist for custom volume copying where an attacker knowing the name of a project that they don't have access to and the name of a custom volume in that project can copy the custom volume to a new project. This issue could allow an attacker to access secrets in custom volumes they are not authorized to access. Version 7.2.0 patches the issue."

      "value": "Incus es un gestor de contenedores de sistema y máquinas virtuales. Antes de la versión 7.2.0, existen comprobaciones de autorización faltantes para la copia de volúmenes personalizados, donde un atacante, conociendo el nombre de un proyecto al que no tiene acceso y el nombre de un volumen personalizado en ese proyecto, puede copiar el volumen personalizado a un nuevo proyecto. Este problema podría permitir a un atacante acceder a secretos en volúmenes personalizados a los que no está autorizado a acceder. La versión 7.2.0 corrige el problema."
