  "title": "Authorization bypass in Arcane backend user updates",
  "summary": "Arcane backend versions through 2.5.0 do not restrict password changes by `users:update` holders based on the target account's privilege level. A delegated user-management account can change the global administrator's password and then access that administrator account. Exploitation requires an authenticated account that has been granted the `users:update` permission.",
  "mitigation": "Upgrade `github.com/getarcaneapp/arcane/backend/v2` to version 2.6.0 or later. Until upgraded, revoke `users:update` from non-administrative roles and review accounts holding that permission.",
