CVE-2018-20007
Yeelight Smart AI Speaker 3.3.10_0074 devices have improper access control over the UART interface, allowing physical attackers to obtain a root shell.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.

The attacker can then exfiltrate the audio data, read cleartext Wi-Fi credentials in a log file, or access other sensitive device and user information.
