CVE-2026-120295 PUBLISHED

Incorrect authorization in the devices page bulk move allows view-role members to move devices into another organization and receive its firmware

Assigner: EEF
Reserved: 06.11.2026 Published: 10.11.2026 Updated: 10.11.2026

Incorrect Authorization vulnerability in the devices page bulk move in nerves-hub nerves_hub_web allows an authenticated user with the manage role in one organization and only the view role in another to move devices into the second organization's product via the "Move device(s) to product" action. The target-product event in NervesHubWeb.Live.Devices.Index looks the product up with NervesHub.Products.get_by_id/2, which checks that the user is a member of the product's organization at any role, and move-devices-product then changes each selected device's organization and product. The device API's move requires manage in the target organization, and an earlier fix added the check on the organization the devices leave but not on the one they enter.

A moved device keeps its key and certificate, joins the target organization's matching deployment groups, and is sent their firmware with a download URL, which the view role cannot otherwise obtain. The user cannot change or control devices that already belong to the other organization.

This issue affects nerves_hub: from 1.0.0 before 2.5.3.

Solutions

Every move is recorded in the target product's audit log as "User moved device to : ". After upgrading, review the audit_logs rows with resource type NervesHub.Products.Product and a description containing "moved device" whose actor does not hold the manage or admin role in that organization, and move or remove the devices they brought in. Roles may have changed since a move, and entries older than the retention period are gone when TRUNCATE_AUDIT_LOGS_ENABLED is on.

Impacts

  • A user who manages devices in one organization and holds only the view role in another can move their own devices into the second organization. The devices join its matching deployment groups and receive its firmware, which the view role cannot otherwise download, and they report health, logs and alarms into that organization. Devices already belonging to the other organization are not affected.
