Summary

A security flaw exists within the Tempo Operator that affects systems utilizing the Jaeger UI Monitor Tab functionality. When this feature is enabled, the Operator incorrectly creates a ClusterRoleBinding for the corresponding Tempo instance's Service Account, granting it access to the cluster-monitoring-view ClusterRole. This vulnerability can be exploited by users with 'create' permissions on TempoStack and 'get' permissions on Secrets in a specified namespace, permitting them to access the token for Tempo's service account. Consequently, these users can view all cluster metrics, leading to potential exposure of sensitive monitoring data.
