CVE-2026-27877: 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.

Security readout for executives and security teams

Plain-English summary

This Grafana issue can expose passwords for direct-mode data sources through public dashboards, even when those data sources are not used by the dashboard. The business risk is credential disclosure, not service outage. Proxied data sources are stated not to expose passwords.

Executive priority

Treat as high priority for internet-facing or partner-accessible Grafana deployments. Prioritize systems with public dashboards and direct datasource credentials, because leaked passwords can enable follow-on access to databases or observability backends.

Technical view

CVE-2026-27877 is a high-severity Grafana information disclosure issue affecting public dashboards with direct data-sources. The CVSS 3.1 score is 7.5, network exploitable, low complexity, no privileges or user interaction, with high confidentiality impact only.

Likely exposure

Exposure is likely where Grafana public dashboards are enabled and direct-mode data sources with passwords exist. The bundle lists Grafana versions 9.3.0, 12.0.0, 12.2.0, 12.3.0, and 12.4.0 as affected, with default status otherwise unaffected.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The risk is still material because the condition is remotely reachable and can disclose stored datasource passwords without authentication or user interaction.

Researcher notes

The vulnerability maps to CWE-201 and CWE-312. Sources identify confidentiality-only impact and state proxied datasource passwords are not exposed. Available bundle evidence does not include exploit artifacts, detailed vulnerable code paths, or exact fixed upstream versions.

Mitigation direction

  • Convert direct data sources to proxied data sources where possible.
  • Review the Grafana advisory for fixed-version or configuration guidance.
  • Review applicable Red Hat errata if using Red Hat-packaged Grafana.
  • Rotate passwords for exposed direct data sources after remediation.
  • Avoid public dashboards that coexist with direct datasource credentials until remediated.

Validation and detection

  • Inventory Grafana instances and versions against the affected list.
  • Identify public dashboards enabled on each Grafana instance.
  • List direct-mode data sources and confirm whether passwords are configured.
  • Confirm proxied data sources are not treated as exposed by this CVE.
  • Check vendor advisories for fixed package status before closure.
