Grafana Labs 12.0.x < 12.4.12 / 13.0.x < 13.0.10 / 13.1.x < 13.1.7 / 13.2.x < 13.2.3 Improper Authorization (CVE-2026-13720)

medium Nessus Plugin ID 362624

Synopsis

The remote host is affected by an improper authorization vulnerability.

Description

The version of Grafana Labs installed on the remote host is 12.0.x through 12.4.x prior to 12.4.12, or 13.0.x prior to 13.0.10, or 13.1.x prior to 13.1.7, or 13.2.x prior to 13.2.3. It is, therefore, affected by an improper authorization vulnerability:

- An Editor can set file-provisioning metadata (the grafana.app/managedBy, grafana.app/managerId and grafana.app/sourcePath annotations) when creating a dashboard through the dashboard API, because these fields were stored without an authorization check. The dashboard then appears file-provisioned, and administrators can no longer update or delete it through Grafana. The impact is limited to the same organization and no data is exposed. (CVE-2026-13720)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update Grafana Labs to 12.4.12, 13.0.10, 13.1.7, 13.2.3 or later.
