CVE-2026-50099

Physical WiFi credential disclosure via exposed UART

Published Jun 12, 2026 · Updated Jun 12, 2026

Information disclosure in all Naxclow IoT Platform versions allows physically proximate attackers to recover WiFi credentials via UART. During WiFi association, the device firmware writes the SSID, PSK, and negotiated WPA keys in cleartext to labeled UART pads using default serial settings. Brief physical access also reaches an interactive RT-Thread shell with arbitrary memory reads, exposing credentials and allowing complete firmware extraction without reported integrity or availability effects.
