CVE-2026-18381: Red Hat Cost Management Metrics Operator

High severity, CVSS 7.6. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
