Doc Text:
A flaw was found in Grafana Live, where a race condition allows authenticated users with a Viewer role to trigger a server crash. By sending concurrent requests, these users can cause a fatal map access error, leading to complete service unavailability (Denial of Service). This requires a restart of the Grafana server to restore service.
