CVE-2026-120295: Incorrect authorization in the devices page bulk move allows view-role members to move devices into another organization and receive its firmware

HighCVSS 7.1 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: nerves-hub nerves_hub_web 1bc8be875ab6b1eb904e5ff60c8a1421c5c700fa, 2.5.3.

Low priority for now. Upgrade to nerves-hub nerves_hub_web 1bc8be875ab6b1eb904e5ff60c8a1421c5c700fa, 2.5.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
