CVE-2026-13719 · Severity: medium · CVSS 4.3 · Published 2026-09-30

Grafana's alert rules API has an authorization flaw that allows authenticated users to view alert rule configurations they should not have access to. When a user has no folder read permissions, the authorization check is dropped entirely, exposing all organization alert rules instead. This could leak sensitive rule configurations including data source details and alerting logic to unauthorized users.

## 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.

## Affected products
