CVE-2020-11921

Device takeover via unencrypted Bluetooth traffic

Published Nov 7, 2024 · Updated Nov 4, 2025

Missing Bluetooth encryption in Lush 2 through 2020-02-25 allows physically proximate attackers to control it via an active phone connection. Bluetooth traffic between the device and paired mobile phone lacks encryption, allowing an attacker within radio range to hijack the ongoing connection and issue device commands. Exploitation requires an existing Bluetooth session and proximity to it; the published record reports full device control but no further impact details.
