  "title": "Cross-organization authorization bypass in nerves_hub",
  "summary": "NervesHub nerves_hub versions before 2.5.3 do not consistently constrain organization-related identifiers to the caller's organization. An authenticated user with a manage role in any organization can create or alter certain records across organization boundaries, potentially causing a device to receive firmware associated with another organization. The attacker must have an account and device-management permissions in their own organization.",
  "mitigation": "Upgrade the NervesHub OCI image and the nerves_hub OTP package to version 2.5.3 or later. Until upgrades are complete, restrict device-management access to trusted users and review cross-organization device, product, deployment-group, signing-key, and JITP associations.",
