Summary
The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.
This Low impact flaw in Grafana allows an authenticated Organization Administrator to delete public dashboards belonging to other organizations. This is due to insufficient isolation enforcement in the public dashboard deletion endpoint, potentially affecting the availability of dashboards in multi-organizational Grafana deployments.
