Prior to 0.13.8, CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex and CapsuleConfiguration.Spec.NodeMetadata.ForbiddenAnnotations.Regex were not validated by the configuration admission webhook, allowing a Cluster Admin to store a malformed regex that later reached regexp.MustCompile in pkg/api/forbidden_list.go through internal/webhook/node/user_metadata.go and crashed the node admission webhook on Node create, update, or patch requests. This issue is fixed in version 0.13.8."

Antes de la versión 0.13.8, CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex y CapsuleConfiguration.Spec.NodeMetadata.ForbiddenAnnotations.Regex no eran validados por el webhook de admisión de configuración, permitiendo a un Administrador de Clúster almacenar una regex mal formada que luego llegaba a regexp.MustCompile en pkg/API/forbidden_list.go a través de internal/webhook/node/user_metadata.go y provocaba el fallo del webhook de admisión de nodos en las solicitudes de creación, actualización o parcheo de nodos. Este problema está solucionado en la versión 0.13.8."
