CVE-2025-56562Public exploitNetwork attack vector

Unauthenticated device interruption via MAC-only API

Published Sep 16, 2025 · Updated Sep 16, 2025

Missing authentication in Signify Wiz Connected 1.9.1 allows remote attackers to interrupt Wiz devices using only a MAC address. The /api/v2/light endpoint accepts a target device's MAC address without authenticating the requester, but the server-side operation causing the interruption is undisclosed. Knowledge of the target MAC address is sufficient; the documented impact is availability-only, while the interruption type is unspecified.
