CVE-2025-2842 - Tempo Operator ClusterRoleBinding Escalation

CVE ID : CVE-2025-2842
Published : April 2, 2025, 12:15 p.m. | 38 minutes ago
Description : A flaw was found in the Tempo Operator. When the Jaeger UI Monitor Tab functionality is enabled in a Tempo instance managed by the Tempo Operator, the Operator creates a ClusterRoleBinding for the Service Account of the Tempo instance to grant the cluster-monitoring-view ClusterRole. This can be exploited if a user has 'create' permissions on TempoStack and 'get' permissions on Secret in a namespace (for example, a user has ClusterAdmin permissions for a specific namespace), as the user can read the token of the Tempo service account and therefore has access to see all cluster metrics.
Severity: 4.3 | MEDIUM
