Naxclow IoT Platform Authorization bypass through User-Controlled key_CVE-2026-42947

{
    "lastseen": "",
    "description": "A flaw in Naxclow's platform\u2019s onboarding workflow allows an attacker to replay a confirm-then-bind sequence to silently reassign a device to an arbitrary account. Because the affected endpoints validate request signatures but do not confirm legitimate ownership, an attacker with any account can take over a device without user interaction while the device remains online and unaware.",
