CVE-2026-80216: High severity Milesight IoT devices (NFC interface) vulnerability
A cleartext transmission of sensitive information vulnerability in the NFC interface of multiple Milesight IoT device models running affected firmware versions allows an unauthenticated attacker with physical proximity to retrieve LoRaWAN ABP NwkSKey and AppSKey values and D2D keys via an NFC read operation. The exposed keys can be used to decrypt LoRaWAN traffic, forge uplink and downlink frames, submit falsified sensor data, issue supported device commands, and cause subsequent legitimate frames to be rejected.

Frequently Asked Questions
Who can exploit this issue?
An unauthenticated attacker must be in physical proximity to an affected device and able to perform an NFC read operation. No prior credentials or user interaction are required.
What is the practical impact if the keys are exposed?
An attacker can retrieve LoRaWAN ABP NwkSKey and AppSKey values and D2D keys. These keys can enable decryption of LoRaWAN traffic, forged uplink or downlink frames, falsified sensor data, supported device commands, and rejection of later legitimate frames.
