CVE-2026-13720: Grafana authorization bypass in dashboard file-provisioning metadata

CVE-2026-13720 · Severity: medium · CVSS 5.4 · Published 2026-09-30

Grafana's dashboard API allows Editors to set internal file-provisioning metadata without authorization checks, making dashboards appear as externally managed even when created through the UI. This prevents administrators from updating or deleting these dashboards within Grafana, causing denial of service to dashboard management. The issue is scoped to a single organization and does not expose sensitive data.

Technologies: Grafana. Vendors: Grafana.

Technical details

An authorization bypass in the Grafana dashboard API fails to validate Editor permissions when setting grafana.app/managedBy, grafana.app/managerId, and grafana.app/sourcePath annotations during dashboard creation. Once these metadata fields are set, the dashboard is treated as file-provisioned, blocking admin modification or deletion through the API. This is a business logic flaw with network attack vector requiring authentication as an Editor role.
