GHSA-5xf3-gmx4-529v Grafana Tempo Operator Vulnerable to Exposure of Sensitive Information to an Unauthorized Actor

• Go github.com/grafana/tempo-operator: < 0.16.0 → fixed in 0.16.0

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.
