Grafana Labs 12.3.x < 12.4.12 / 13.0.x < 13.0.10 / 13.1.x < 13.1.7 / 13.2.x < 13.2.3 Information Disclosure (CVE-2026-13719)

medium Nessus Plugin ID 362626

Synopsis

The remote host is affected by an information disclosure vulnerability.

Description

The version of Grafana Labs installed on the remote host is 12.3.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 information disclosure vulnerability:

- An authenticated user can list alert rules stored in folders they are not allowed to read through the alert rules API list endpoint. When the set of folders the user may read was empty, the folder restriction was dropped and every alert rule in the organization was returned. From Grafana 13.1.0, any user can trigger this with a folder filter. The exposed data is rule configuration; data source credentials are not exposed. (CVE-2026-13719)

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.
