CVE-2026-17183 Grafana CVE debrief

AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-19T18:16:35.940Z and has not been modified since then. This CVE-2026-17183 vulnerability allows an authenticated user with permission to create or edit alert rules to bypass datasource query authorization. The user can do this by marking an alert rule query as a server-side expression while referencing a real datasource UID. As a result, users who lack permission to query that datasource may be exposed to data accessible through Grafana's configured datasource credentials. The issue has a CVSS score of 7.1 and is classified as HIGH severity. To mitigate this vulnerability, it is essential to review and restrict permissions for creating or editing alert rules, monitor for unauthorized datasource queries, verify alert rules do not use server-side expressions with real datasource UIDs, restrict access to sensitive data sources, and implement additional logging and monitoring for datasource queries.

Who should care

Grafana administrators, users with permission to create or edit alert rules, and security teams monitoring for unauthorized datasource queries should be aware of this vulnerability and take steps to mitigate it.

Technical summary

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. This can expose data accessible through Grafana's configured datasource credentials to users who lack permission to query that datasource. The issue has a CVSS score of 7.1 and is classified as HIGH severity.

Defensive priority

Authenticated users with permission to create or edit alert rules may bypass datasource query authorization, potentially exposing data accessible through Grafana's configured datasource credentials. Monitor for unauthorized datasource queries and review alert rules for server-side expressions referencing real datasource UIDs.

Recommended defensive actions

  • Review and restrict permissions for creating or editing alert rules
  • Monitor for unauthorized datasource queries
  • Verify alert rules do not use server-side expressions with real datasource UIDs
  • Restrict access to sensitive data sources
  • Implement additional logging and monitoring for datasource queries

Evidence notes

The CVE record indicates 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.
