## Overview

A flaw was found in koku-metrics-operator. The operator's CostManagementMetricsConfig custom resource allows user able to edit the CR to specify an arbitrary upload URL. When authentication.type is set to token (the default), the cluster-global Red Hat Cloud pull-secret bearer token is attached to HTTP requests sent to this user-controlled URL, allowing the attacker to obtain the token.
