Project-koku/koku-metrics-operator: koku-metrics-operator: operator service-account token exfiltration via user-controlled prometheus service_address PUBLISHED

Description (CNA)

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.
