What is CVE-2025-59448?
CVE-2025-59448 is a medium-severity vulnerability in YoSmart YoLink ecosystem, published on 6 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-319
