  "summary": "Nautobot's Jinja2 template sandbox can fail to protect sensitive model fields when templates use named attribute lookups through certain filters or methods. An authenticated user permitted to create or edit user-authored templates may expose another reachable user's password hash or, under the default sensitive-field setting, API token key; a stolen token can enable access as that user.",
  "mitigation": "Upgrade Nautobot to 2.4.46 or later, or 3.2.9 or later. Until upgraded, limit user-authored template permissions to trusted administrators, review existing templates for unexpected field-access behavior, and rotate potentially exposed credentials.",
