If you cannot patch yet, users should consider disabling the Wi-Fi hotspot if possible or placing the device in a secure network environment to reduce exposure. Avoid connecting to unknown or untrusted networks through the device's hotspot.
Description
The ECOVACS ROBOTICS DEEBOT PRO M1 and DEEBOT PRO K1VAC models use weak passwords for their Wi-Fi hotspot networks. This weakness allows an attacker to analyze and obtain the password to connect to the robot's access point. The vulnerability has a medium severity rating with a CVSS score of 5.3, indicating limited confidentiality impact without affecting integrity or availability.
