CVE-2026-42947

Naxclow IoT Platform Authorization bypass through User-Controlled key

Published Jun 12, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
A flaw in Naxclow's platform’s 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.
