CVE-2026-17183: CWE-863: INCORRECT AUTHORIZATION in Grafana Grafana OSS
Description
CVE-2026-17183 is a high-severity vulnerability in Grafana OSS where 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 referencing a real datasource UID, the user can access data through Grafana's datasource credentials without proper permission. This incorrect authorization flaw can expose sensitive data to unauthorized users.

Technical Analysis
This vulnerability (CWE-863) in Grafana OSS allows an authenticated user who can create or edit alert rules to bypass datasource query authorization controls. The user achieves this by marking an alert rule query as a server-side expression while referencing a valid datasource UID. This bypass exposes data accessible via Grafana's configured datasource credentials to users lacking explicit permission to query that datasource. The CVSS 3.1 score is 7.1 (high), reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, high confidentiality impact, low integrity impact, and no availability impact. Affected versions include >=8.4.0 <12.3.11, >=12.4.0 <12.4.9, >=13.0.0 <13.0.7, >=13.1.0 <13.1.4, and =8.4.0.
Potential Impact
An attacker with authenticated access and permission to create or edit alert rules can access sensitive data from datasources they are not authorized to query. This leads to unauthorized data disclosure, impacting confidentiality. Integrity and availability impacts are low or none.
Mitigation Recommendations
No explicit patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the official Grafana vendor advisory for current remediation guidance. Until patched, restrict permissions to create or edit alert rules to trusted users only.
