Mitigation checklist
- To mitigate this issue, disable the Geomap plugin. This can be achieved by setting `disable_plugins = geomap` in the `[plugins]` section of the `grafana.ini` configuration file, or by setting the environment variable `GF_PLUGINS_DISABLE_PLUGINS=geomap`. A restart of the Grafana service is required for the changes to take effect. Disabling the plugin will remove the Geomap panel and may affect existing dashboards that utilize it.
