CVE-2025-59448
Components of the YoSmart YoLink ecosystem through 2025-10-02 leverage unencrypted MQTT to communicate over the internet. An attacker with the ability to monitor network traffic could therefore obtain sensitive information or tamper with the traffic to control affected devices. This affects YoLink Hub 0382, YoLink Mobile Application 1.40.41, and YoLink MQTT Broker. NOTE: The vendor states that the vulnerability described (related to insecure transmission) only impacts the legacy mobile application logic, not the Hub hardware or firmware. The Hub functions solely as a pass-through (transparent gateway) for LoRa wireless data and does not inspect or process the application layer data.
CVE-2025-59449
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.
CVE-2025-59450
The YoSmart YoLink Smart Hub firmware 0382 is unencrypted, and data extracted from it can be used to determine network access credentials.
CVE-2025-59451
The YoSmart YoLink application through 2025-10-02 has session tokens with unexpectedly long lifetimes.
CVE-2025-59447
The YoSmart YoLink Smart Hub device 0382 exposes a UART debug interface. An attacker with direct physical access can leverage this interface to read a boot log, which includes network access credentials.
