Description

The YoSmart YoLink MQTT broker through 2025-10-02 does not enforce sufficient authorization controls to prevent cross-account attacks, allowing an attacker to remotely operate affected devices if the attacker obtains the associated device IDs. Because YoLink device IDs are predictable, an attacker can exploit this to gain full control over any other YoLink user's devices.

Attack-Flow Graph

Executive Summary

This vulnerability in the YoSmart YoLink MQTT broker allows attackers to remotely control devices belonging to other users by exploiting insufficient authorization controls. Since device IDs are predictable, an attacker who obtains these IDs can perform cross-account attacks and gain full control over affected devices.

Impact Analysis

If exploited, this vulnerability can allow an attacker to remotely operate your YoLink devices without your permission, potentially leading to unauthorized control and misuse of your smart devices.
