MediumCVSS 5.8Exploitation Probability (EPSS)
Low risk36th percentile - higher than 36% of all known CVEs
Summary
The YoSmart YoLink API through 2025-10-02 uses an endpoint URL derived from a device's MAC address along with an MD5 hash of non-secret information, such as a key that begins with cf50.
Risk Assessment
Weak endpoint generation could allow an attacker to predict or manipulate device communication, potentially leading to unauthorized access or control.
Recommendation
Update the YoLink API to a newer version that uses more secure endpoint generation methods.
