CVE-2026-17183: Grafana Enterprise

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

An authenticated user with permission to create or edit alert rules can bypass datasource query authorization by marking an alert rule query as a server-side expression while referencing a real datasource UID (incorrect authorization). This can expose data accessible through Grafana's configured datasource credentials to users who lack permission to query that datasource.
