A flaw was found in Grafana. When public dashboards are used with direct data-sources, sensitive credentials, specifically passwords for all direct data-sources, are exposed. This information disclosure occurs even when these data-sources are not actively utilized in the dashboards. A remote attacker could exploit this to gain unauthorized access to other systems.

Description OSIDB Bzimport 2026-03-27 15:03:57 UTC
When using public dashboards and direct data-sources, all direct data-sources' passwords are exposed despite not being used in dashboards.

No passwords of proxied data-sources are exposed. We encourage all direct data-sources to be converted to proxied data-sources as far as possible to improve your deployments' security.
