      "value": "Gardener External DNS Management is an environment to manage external DNS entries for a kubernetes cluster. A security vulnerability was discovered in Gardener's External DNS Management prior to version 0.23.6 that could allow a user with administrative privileges for a Gardener project or a user with administrative privileges for a shoot cluster, including administrative privileges for a single namespace of the shoot cluster, to obtain control over the seed cluster where the shoot cluster is managed. This CVE affects all Gardener installations no matter of the public cloud provider(s) used for the seed clusters/shoot clusters. The affected component is `gardener/external-dns-management`. The `external-dns-management` component may also be deployed on the seeds by the `gardener/gardener-extension-shoot-dns-service` extension when the extension is enabled. In this case, all versions of the `shoot-dns-service` extension `<= v1.60.0` are affected by this vulnerability. Version 0.23.6 of Gardener External DNS Management fixes the issue."

      "value": "Gardener External DNS Management es un entorno para administrar entradas DNS externas en un clúster de Kubernetes. Se descubrió una vulnerabilidad de seguridad en la Administración de DNS Externa de Gardener anterior a la versión 0.23.6 que podría permitir que un usuario con privilegios administrativos para un proyecto de Gardener o para un clúster de brotes, incluyendo privilegios administrativos para un único espacio de nombres del clúster de brotes, obtuviera control sobre el clúster de semillas donde se administra dicho clúster. Esta CVE afecta a todas las instalaciones de Gardener, independientemente del proveedor de nube pública utilizado para los clústeres de semillas/brotes. El componente afectado es `gardener/external-dns-management`. El componente `external-dns-management` también puede implementarse en las semillas mediante la extensión `gardener/gardener-extension-shoot-dns-service` cuando esta está habilitada. En este caso, todas las versiones de la extensión `shoot-dns-service` &lt;= v1.60.0` se ven afectadas por esta vulnerabilidad. La versión 0.23.6 de Gardener External DNS Management soluciona el problema."
