CVE-2026-39430 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked.

## Summary

HP Poly EagleEye Cube USB devices running firmware 1.3.1-001267 have a broken administrator login flow, because the device does not enforce session management or access controls on its admin functions. An unauthenticated attacker can skip the login step, using a modified or custom client to call the administrator API directly, change administrator-level settings, and export configuration files that contain the internal administrator and other network credentials.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

No affected packages have been listed by the sources.

## Description

On HP Poly EagleEye Cube USB 1.3.1-001267 devices, the administrator authentication flow is broken: session management and access controls are not enforced device-side. Thus, an unauthenticated user can change administrator-level settings (without logging in) via a modified client that bypasses the login step or via a custom client to make the underlying administrator API calls. This allows unauthenticated users to perform administrative actions too such as exporting configuration files that include the internal device credentials for the administrator user and other network systems.
