"The version of Grafana Labs installed on the remote host is affected by an improper access control vulnerability as 
referenced in the CVE-2025-3580 advisory. 

  - 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. (CVE-2025-3580)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
