Technical details
The vulnerability exists in Grafana's shared dashboard functionality where pausing a public dashboard does not invalidate its access token for bootstrap data endpoints. An unauthenticated attacker can send requests to these endpoints using the dashboard link to retrieve dashboard configuration including data source credentials stored for browser access. Only deletion of the dashboard revokes the token; access control checks are missing from the relevant endpoints.
