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.

Summary		(es) Los componentes del ecosistema YoSmart YoLink hasta el 02-10-2025 utilizan MQTT sin cifrar para comunicarse a través de internet. Un atacante con la capacidad de monitorear el tráfico de red podría, por lo tanto, obtener información sensible o manipular el tráfico para controlar los dispositivos afectados. Esto afecta a YoLink Hub 0382, la Aplicación Móvil YoLink 1.40.41 y YoLink MQTT Broker. NOTA: El proveedor afirma que la vulnerabilidad descrita (relacionada con la transmisión insegura) solo afecta la lógica de la aplicación móvil heredada, no el hardware o el firmware del Hub. El Hub funciona únicamente como un paso a través (puerta de enlace transparente) para datos inalámbricos LoRa y no inspecciona ni procesa los datos de la capa de aplicación.
