      "value": "Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An insecure default `Access-Control-Allow-Origin` header value could lead to sensitive data exposure for users of Cilium versions 1.14.0 through 1.14.7, 1.15.0 through 1.15.11, and 1.16.0 through 1.16.4 who deploy Hubble UI using either Cilium CLI or via the Cilium Helm chart. A user with access to a Hubble UI instance affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is monitoring, including node names, IP addresses, and other metadata about workloads and the cluster networking configuration. In order for this vulnerability to be exploited, a victim would have to first visit a malicious page. This issue is fixed in Cilium v1.14.18, v1.15.12, and v1.16.5. As a workaround, users who deploy Hubble UI using the Cilium Helm chart directly can remove the CORS headers from the Helm template as shown in the patch from commit a3489f190ba6e87b5336ee685fb6c80b1270d06d."

      "value": "Cilium es una solución de seguridad, observabilidad y redes con un plano de datos basado en eBPF. Un valor de encabezado `Access-Control-Allow-Origin` predeterminado inseguro podría provocar la exposición de datos confidenciales para los usuarios de las versiones de Cilium 1.14.0 a 1.14.7, 1.15.0 a 1.15.11 y 1.16.0 a 1.16.4 que implementan Hubble UI mediante la CLI de Cilium o mediante el gráfico Helm de Cilium. Un usuario con acceso a una instancia de Hubble UI afectada por este problema podría filtrar detalles de configuración sobre el clúster de Kubernetes que Hubble UI está monitoreando, nombres de nodos incluida, direcciones IP y otros metadatos sobre cargas de trabajo y la configuración de red del clúster. Para que se aproveche esta vulnerabilidad, la víctima primero tendría que visitar una página maliciosa. Este problema se solucionó en Cilium v1.14.18, v1.15.12 y v1.16.5. Como workaround, los usuarios que implementan Hubble UI usando el gráfico Helm de Cilium directamente pueden eliminar los encabezados CORS de la plantilla Helm como se muestra en el parche de commit a3489f190ba6e87b5336ee685fb6c80b1270d06d."
