CVE-2026-18381

A flaw was found in the koku-metrics-operator for Red Hat OpenShift. The operator's CostManagementMetricsConfig custom resource allows a user able to edit the CR to specify an arbitrary upload URL. The operator attaches its own Kubernetes service-account bearer token to queries sent to this user-controlled URL, allowing the attacker to obtain the token.

Summary		(es) Se encontró una falla en el koku-metrics-operator para Red Hat OpenShift. El recurso personalizado CostManagementMetricsConfig del operador permite a un usuario capaz de editar el CR especificar una URL de carga arbitraria. El operador adjunta su propio token portador de cuenta de servicio de Kubernetes a las consultas enviadas a esta URL controlada por el usuario, permitiendo al atacante obtener el token.
