Vulnerability Title
Project-koku/koku-metrics-operator: koku-metrics-operator: cluster pull-secret token exfiltration via user-controlled api_url (ssrf / confused deputy)
Source: CVE Program / CVE List V5
Vulnerability Description
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.
