# CVE-2026-50101

> 9.2 CRITICAL · 🧪 PoC

## Beschreibung

Naxclow devices use a server-side, per-device relay credential that never rotates and is re-issued to the device on each boot. Because this credential remains valid indefinitely and cannot be reset or revoked by the legitimate owner, any party that obtains it through any exposure path can maintain persistent access to the device’s relay channel. This enables long-term impersonation or interception, even after factory resets or re-onboarding.
