Technical details
The alert rules API list endpoint fails to properly enforce folder-based access controls when a user's readable folder set is empty. The vulnerability exists in Grafana 13.1.0 and later when users apply a folder filter parameter. An authenticated attacker can invoke the API to enumerate and read alert rule metadata that should be restricted by folder permissions; data source credentials themselves are not exposed.
