CVE-2019-17627 describes a vulnerability in the Yale Bluetooth Key mobile application that allows unauthorized unlocking of Yale ZEN-R and potentially other locks. An attacker can sniff Bluetooth Low Energy (BLE) traffic during a legitimate unlock, then compute the authentication key through simple hexadecimal manipulation. This medium-severity vulnerability (CVSS 6.5) requires physical proximity (adjacent network access) and has high confidentiality impact, but no known public exploits, Metasploit modules, or significant community discussion have been identified.
