CVE-2026-42932Network attack vector

Fleet enumeration via predictable device identifiers

Published Jun 12, 2026 · Updated Jun 12, 2026

Predictable identifiers in Naxclow Smart Doorbell X3, X Smart Home, V720, and ix cam allow remote attackers to enumerate devices. The platform combines fixed manufacturing prefixes with sequential counters and exposes an endpoint that reveals the current identifier high-water mark. Network access without authentication is sufficient to map the active fleet, but the cited record reports no ability to modify devices or interrupt service.
