Grafana Direct Data-source Password Disclosure in Public Dashboards
CVE-2026-27877 Published on March 27, 2026
Public dashboards discloses all direct mode datasources
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.
Weakness Type
Cleartext Storage of Sensitive Information
The application stores sensitive information in cleartext within a resource that might be accessible to another control sphere. Because the information is stored in cleartext, attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.
