Title
Project-koku/koku-metrics-operator: koku-metrics-operator: cluster pull-secret token exfiltration via user-controlled api_url (ssrf / confused deputy)
Summary
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.
Severity
7.6 (High)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N
