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

Grafana public dashboards can expose passwords for every configured direct-mode data source, even when those sources are not used by the dashboard. An unauthenticated remote visitor may obtain credentials and use them against connected systems. Proxied data-source passwords are not exposed.

Executive priority

Treat as a high-priority credential exposure for environments combining public dashboards with direct data sources. Promptly identify affected deployments, reduce public access, follow Grafana's remediation guidance, and rotate potentially disclosed credentials. Proxied-only deployments have lower urgency for this specific flaw.

Technical view

CVE-2026-27877 is an unauthenticated network-accessible information disclosure affecting Grafana public dashboards with direct data sources. It carries CVSS 3.1 score 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and maps to CWE-201 and CWE-312. The supplied record lists versions 9.3.0, 12.0.0, 12.2.0, 12.3.0, and 12.4.0; precise ranges require vendor confirmation.

Likely exposure

Exposure requires both public dashboards and configured direct-mode data sources. All direct data-source passwords may be disclosed, regardless of dashboard usage. Deployments using only proxied data sources are not exposed through this issue. Internet-accessible public dashboards present the greatest business risk.

Exploitation context

The supplied record does not identify known active exploitation and marks the CVE as absent from KEV. Exploitation requires no authentication, privileges, or user interaction, but the bundle provides no evidence about public exploit availability or observed attacks.

Researcher notes

The central condition is configuration-dependent disclosure, not compromise of proxied data sources. The supplied affected-version data is incomplete or ambiguous because it lists discrete versions while assigning a default status of unaffected. Confirm exact affected and fixed ranges with Grafana. No integrity or availability impact is asserted by the CVSS vector.

Mitigation direction

  • Convert direct data sources to proxied data sources wherever possible.
  • Consult Grafana's advisory for applicable fixed versions and upgrade guidance.
  • Disable unnecessary public dashboards until remediation is verified.
  • Rotate passwords for potentially exposed direct data sources.
  • Restrict affected credentials and monitor connected systems for misuse.

Validation and detection

  • Inventory Grafana versions and compare them with Grafana's current advisory.
  • Identify every public dashboard and configured direct-mode data source.
  • Confirm public dashboards cannot reveal direct data-source credentials after remediation.
  • Review access logs for unexpected public-dashboard requests or data-source access.
  • Verify rotated credentials no longer authenticate to connected systems.
