CVE-2025-3580
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn access control vulnerability was discovered in Grafana OSS where an Organization administrator could permanently delete the Server administrator account. This vulnerability exists in the DELETE /api/org/users/ endpoint. The vulnerability can be exploited when: 1. An Organization administrator exists 2. The Server administrator is either: - Not part of any organization, or - Part of the same organization as the Organization administrator Impact: - Organization administrators can permanently delete Server administrator accounts - If the only Server administrator is deleted, the Grafana instance becomes unmanageable - No super-user permissions remain in the system - Affects all users, organizations, and teams managed in the instance The vulnerability is particularly serious as it can lead to a complete loss of administrative control over the Grafana instance.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn access control flaw in Grafana OSS allows an Organization administrator to delete the Server administrator account via the DELETE /api/org/users/ endpoint. The vulnerability occurs because the endpoint does not properly verify that the requesting user lacks permission to remove the highest-privilege administrative account, enabling org admins to permanently delete server admins when the server admin is either unassigned to any organization or shares the same organization.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Grafana OSS versionQuery the Grafana instance for its version using the /api/health endpoint or check the grafana-server process/package versionAffected if The installed version is any Grafana OSS version that has the DELETE /api/org/users/ endpoint and contains Organization Administrator and Server Administrator role types
-
Identify Organization Administrator accountsQuery the Grafana API using an authenticated session with admin privileges to list users with Organization Administrator role: GET /api/org/users/ or inspect user role assignments in Grafana's user administration interfaceAffected if There exists at least one user granted the Organization Administrator role in any organization
-
Identify Server Administrator accountsQuery Grafana's user administration for users with Server Admin role: GET /api/admin/users/ or inspect Grafana's server user administration panelAffected if There exists at least one user granted the Server Administrator role, particularly if that server admin is either unassigned to any organization or shares an organization with an Organization Administrator
-
Review audit logs for deletion eventsInspect Grafana's audit logs or logs for HTTP DELETE requests to /api/org/users/ endpoint. Check logs for events where an Organization Administrator may have removed a userAffected if Audit logs show DELETE /api/org/users/ calls that resulted in removal of a Server Administrator account, or logs indicate such deletions have occurred in the past
Your environment is affected if you run a Grafana OSS version with the DELETE /api/org/users/ endpoint and have both Organization Administrator accounts and Server Administrator accounts where the server admin is either organization-unassigned or shares an organization with an org admin.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement authorization checks in the DELETE /api/org/users/ endpoint to prevent Organization administrators from deleting Server administrator accounts, regardless of organization membership. Until a patch is applied, limit the creation of Organization administrators and monitor for unauthorized admin account deletion.
