Mitigation checklist
- Restrict query permissions on configured Azure Monitor data sources exclusively to trusted users, or remove the data source configuration entirely if it is not in active use. 1. Within the Grafana administration interface, open the Azure Monitor data source settings and adjust permissions to limit query access only to trusted administrative roles. 2. If Azure Monitor is no longer needed, remove the data source configuration from Grafana. 3. At the cloud provider level, reduce permissions assigned to the Azure identity or service principal used by Grafana to enforce the principle of least privilege. Caveats: Restricting query access or deleting the data source will prevent non-administrative users from viewing dashboards, panels, or alerts that rely on Azure Monitor metrics.
