CVE-2026-50101 Naxclow CVE debrief

A critical vulnerability, CVE-2026-50101, has been identified in Naxclow devices. The issue arises from a server-side, per-device relay credential that is re-issued to the device on each boot and remains valid indefinitely. This allows any party that obtains the credential through any exposure path to maintain persistent access to the device's relay channel, enabling long-term impersonation or interception, even after factory resets or re-onboarding.
