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.","state":0,"publishedAt":"2026-10-26T14:43:29.943+00:00","modifiedAt":"2026-10-27T10:14:05.557+00:00","affected":[{"ecosystem":"Vendor product","name":"TTLock","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Sciener\",\n                    \"product\": \"TTLock\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"9.8.260718\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://damiri.fr/en/cve/CVE-2026-112345","https://www.vulncheck.com/advisories/ttlock-android-app-hardcoded-ble-pairing-key-exposure"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112345","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112345","identifiers":["CVE-2026-112345"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
