CVE-2018-20958
The Bluetooth Low Energy (BLE) subsystem on Tapplock devices before 2018-06-12 relies on Key1 and SerialNo for unlock operations; however, these are derived from the MAC address, which is broadcasted by the device.
Does this matter?
Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.
