CVE-2026-112345 Details
Description
TTLock Android application before v9.8.260718 and associated smart-lock firmware contain a hardcoded static AES key vulnerability that allows an attacker within Bluetooth range to decrypt the per-pairing session key transmitted during BLE pairing. Attackers can observe the pairing exchange, recover the persistent session key using the embedded defaultKey, and forge authenticated BLE requests to unlock the device, add fingerprints or access codes, and perform administrative actions without authentication or user interaction.
A vulnerability exists in the TTLock Android application versions prior to 9.8.260718 and in the associated smart-lock firmware. This vulnerability involves a hardcoded static AES key that enables an attacker within Bluetooth range to decrypt the per-pairing session key transmitted during Bluetooth Low Energy (BLE) pairing. By observing the pairing exchange, attackers can recover the persistent session key using the embedded defaultKey. This allows them to forge authenticated BLE requests to unlock the device, add fingerprints or access codes, and perform administrative actions without authentication or user interaction.
Users are advised to update the TTLock Android application to version 9.8.260718 or later.
