CVE-2026-120730
Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in the device API, device forms, signing key and product forms and JITP settings in nerves-hub nerveshubweb allows an authenticated user who manages devices in any organization to write into other organizations via submitted orgid, productid and deploymentid fields. The device API create and update actions and the dashboard device forms pass the request parameters to NervesHub.Devices.Device.changeset/2, which casts the organization, product, deployment group and update state as given. The signing key and product forms merge the session's organization into the submitted parameters so that a submitted orgid wins, and the JITP changeset accepts any productid. Each request requires the manage role only in the user's own organization, and any account can create one. A device placed on another organization's deployment group, or moved into its product, is sent that organization's firmware with a download URL. The user cannot change or control devices that already belong to the other organization, and cannot upload firmware to it. This issue affects nerveshub: from 1.0.0 before 2.5.3.
