CVE-2026-92539 Grafana CVE debrief

A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API (insecure direct object reference). Only Grafana Enterprise instances with SCIM enabled are affected. This vulnerability allows unauthorized user modification across organizations, potentially leading to security breaches. Administrators should verify SCIM status and restrict user-management permissions to prevent such incidents.

Who should care

Grafana Enterprise administrators and security teams should assess exposure and verify SCIM status to prevent unauthorized user modification across organizations. They should review user-management settings, monitor for suspicious activity, and restrict permissions as needed to protect against potential security breaches. Immediate action is recommended due to the vulnerability's severity and potential impact.

Why it matters

Grafana Enterprise administrators should verify SCIM status and restrict user-management permissions to prevent unauthorized user modification across organizations.

  • Verify SCIM status to prevent unauthorized user modification
  • Restrict user-management permissions to prevent cross-organization access
  • Monitor for unauthorized user modification across organizations
  • Review user-management settings for Grafana Enterprise instances

Technical summary

A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API. Only Grafana Enterprise instances with SCIM enabled are affected. This insecure direct object reference vulnerability allows unauthorized access to user data across organizations, emphasizing the need for strict access controls and monitoring. No patch is available, but mitigations include verifying SCIM status and restricting user-management permissions.

Defensive priority

Grafana Enterprise administrators should verify SCIM is disabled or restrict user-management permissions to prevent unauthorized user modification across organizations.

Recommended defensive actions

  • Verify SCIM is disabled or restrict user-management permissions
  • Review user-management settings for Grafana Enterprise instances
  • Monitor for unauthorized user modification across organizations
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE Program record and NVD vulnerability detail provide official information about the vulnerability. The Grafana security advisory offers additional context. Evidence is limited, and defenders should verify SCIM status and user-management permissions to assess exposure. No exploit details are publicly available, but the vulnerability's severity suggests immediate attention.
