Doc Text:
A flaw was found in nerves_hub_web. An authenticated user with device management permissions in their own organization can manipulate organization and product identifiers submitted through web forms and API requests. This enables the user to assign their devices to another organization's deployment group or product, resulting in unauthorized cross-tenant information disclosure through the delivery of unintended firmware download URLs.

Description OSIDB Bzimport 2026-11-10 20:12:15 UTC 
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 nerves_hub_web allows an authenticated user who manages devices in any organization to write into other organizations via submitted org_id, product_id and deployment_id 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 org_id wins, and the JITP changeset accepts any product_id. 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 nerves_hub: from 1.0.0 before 2.5.3.
