## Description

An 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.

## What to do

- Check your stack: if you ship or depend on Grafana, upgrade to a fixed version (12.0.1, 11.6.2, 11.5.5, 11.4.5, 11.3.7) per the references below.
