CVE-2026-112345
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
TTLock Android application before v9.8.260718 and associated smart-lock firmware contain a hardcoded static AES key that lets an attacker within Bluetooth range decrypt the per-pairing session key transmitted during BLE pairing. Attackers can observe the pairing exchange, recover the persistent session key, and forge authenticated BLE requests to unlock the device, add fingerprints or access codes, and perform administrative actions without authentication or user interaction.
Risk Assessment
A person within Bluetooth range can gain unauthorized physical access to protected areas and modify lock credentials. This poses a serious threat to physical security and access control.
Recommendation
Update the TTLock app to v9.8.260718 or later and update lock firmware to a version that removes the hardcoded key. Until patched, limit reliance on TTLock locks in high-risk areas.

SEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment metadata. An unauthenticated remote sender can cause the mail-processing worker to disclose, move, or delete an accessible regular file when LFT is enabled and the message reaches an affected secure-mail processing path. The validated workers ran as root.

SEPPmail Secure Email Gateway before 15.1.1 can evaluate attacker-influenced replacement text as Perl code in sender or recipient replacement rules. An unauthenticated remote sender can execute operating-system commands in the mail-processing worker context when an active rule uses message-derived replacement data and its search condition matches. The validated worker context was root.

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.
