CVE-2026-16454 Eclipse Foundation CVE debrief

CVE-2026-16454 is a medium-severity privilege escalation vulnerability in Eclipse hawkBit versions 1.0.3 and prior. The vulnerability exists in the Direct Device Integration (DDI) Controller and allows an authenticated device to escalate its permissions and bypass update restrictions. This issue stems from flawed object-level authorization validation, enabling any authenticated device within the same tenant to download any firmware artifact, bypassing assigned update restrictions. A related issue exists in the software modules artifacts metadata endpoint, enabling enumeration of available firmware artifacts. Users of Eclipse hawkBit versions 1.0.3 and prior should apply patches or mitigations to prevent exploitation of this vulnerability.

Who should care

Users of Eclipse hawkBit versions 1.0.3 and prior should apply patches or mitigations to prevent exploitation of this vulnerability. This includes administrators and security teams responsible for managing and securing Eclipse hawkBit deployments. They should review the official advisory and CVE record to validate affected scope, severity, and vendor guidance.

Technical summary

The vulnerability, identified as CWE-284 and CWE-862, stems from flawed object-level authorization validation in the DDI Controller. This allows any authenticated device within the same tenant to download any firmware artifact, bypassing assigned update restrictions. A related issue exists in the software modules artifacts metadata endpoint, enabling enumeration of available firmware artifacts. The issue is not an authentication bypass; the requesting device must possess valid credentials for its respective tenant.

Defensive priority

High

Recommended defensive actions

  • Apply patches or updates provided by the vendor to address the vulnerability
  • Implement compensating controls to restrict access to firmware artifacts
  • Monitor for suspicious activity related to firmware downloads and updates
  • Conduct regular inventory checks to ensure all devices are running authorized firmware
  • Review and update security policies to include checks for affected product deployments
  • Verify that all devices are running authorized firmware and track exceptions
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
