A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs.
Se ha detectado un problema de seguridad en Kubernetes en el que un usuario puede ser capaz de redirigir el tráfico del pod a redes privadas en un Nodo. Kubernetes ya previene la creación de IPs de Endpoint en el rango localhost o link-local, pero no se ha llevado a cabo la misma comprobación en las IPs de EndpointSlice.
