Exploitable ClusterRoleBinding Escalation in Grafana Tempo Operator
CVE-2025-2842 Published on April 2, 2025
Tempo-operator: tempo operator token exposition lead to read sensitive data
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.
