CVE-2026-17183

A flaw was found in Grafana's Unified Alerting component. An authenticated user with permissions to create or edit alert rules in a folder can bypass datasource query permissions. By manipulating the `queryType` field, an attacker can execute queries against datasources they are not authorized to access, leading to the disclosure of sensitive data. This vulnerability arises from inconsistent query classification between authorization and execution paths.
