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.");
