Due to missing network isolation a shoot's apiserver can access services/endpoints in the private network of its corresponding seed cluster. Combined with other minor Kubernetes security issues, the missing network isolation theoretically can lead to compromise other shoot or seed clusters in the \"Gardener\" context. The issue is rated high due to the high impact of a potential exploitation in \"Gardener\" context. This was fixed in Gardener release 0.12.4."}, {"lang": "es", "value": "Siguiendo la arquitectura de Gardener, el apiserver de Kubernetes de una semilla del cl\u00faster gestionado por Gardener reside en la semilla del cl\u00faster correspondiente.

En combinaci\u00f3n con otros problemas de seguridad menores de Kubernetes, el aislamiento de la red ausente te\u00f3ricamente puede comprometer otras semillas del cl\u00faster o \"shoots\" en el contexto \"Gardener\".
