Doc Text:
A flaw was found in Grafana. An authenticated user can query the alert rules list Application Programming Interface (API) to access alert rules stored in restricted folders they lack permission to read. When access restrictions are evaluated and a user has no readable folders, folder filtering is dropped and all alert rules within the organization are returned. This flaw results in unauthorized information disclosure of alert rule configurations, though data source credentials are not exposed.

Description OSIDB Bzimport 2026-09-30 11:26:03 UTC
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.
