• CVE-2026-16454: 0.36% estimated exploitation activity in the next 30 days; percentile 29.65 (FIRST EPSS, 2026-11-10). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Description A privilege escalation vulnerability has been identified in the Direct Device Integration (DDI) Controller of Eclipse hawkBit (versions 1.0.3 and prior). This vulnerability allows an authenticated device to escalate its permissions and bypass the strict boundaries of its assigned updates. Under normal operation, a device should be restricted strictly to the specific firmware artifacts explicitly assigned to it. However, this flaw enables any authenticated device to bypass this restriction and download any firmware artifact within the same tenant. This is not an authentication bypass; the requesting device must possess valid credentials for its respective tenant. Instead, the issue stems from a flaw in object-level authorization validation. A related, lower-severity helper issue exists in the listing software modules artifacts metadata endpoint. This endpoint does not enforce assignment checks, enabling an authenticated device to list and enumerate…

# Patch Next advisory brief: CVE-2026-16454

Advisory: Eclipse hawkBit DDI has Privilege Escalation that allows Tenant-Isolated Firmware Exfiltration
IDs: CVE-2026-16454, GHSA-92r3-p8c2-3fpx
Record: https://patchnext.com/advisories/cve-2026-16454 (revision 2, source checked 7 Nov 2026, 06:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.eclipse.hawkbit:hawkbit-ddi-resource 1.0.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.eclipse.hawkbit:hawkbit-ddi-resource: affected < 1.0.4; fixed in 1.0.4

## Suggested inspection (read-only)
- Maven org.eclipse.hawkbit:hawkbit-ddi-resource: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.eclipse.hawkbit:hawkbit-ddi-resource.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
