  "details" : [ "An Editor can overwrite a dashboard not owned by them to acquire admin on that specific dashboard. The user must have write access to the dashboard to escalate privilege.", "A flaw was found in Grafana. A user with editor privileges can overwrite a dashboard not owned by them, leading to privilege escalation on that specific dashboard. This allows the editor to gain administrative control over the affected dashboard." ],
  "statement" : "A privilege escalation flaw exists in Grafana, allowing an authenticated editor with write access to a dashboard to overwrite other dashboards not owned by them. This grants the editor administrative control over the targeted dashboard, potentially leading to unauthorized data manipulation or exposure within the Grafana environment.\nRed Hat's default deployment does not grant edit access to normal users. Hence, this is rated moderate.",
