CVE-2023-50129Public exploit

Physical entry via clonable unencrypted NFC tags

Published Jan 11, 2024 · Updated Jun 20, 2025

Missing encryption in NFC tags in Flient Smart Door Lock 1.0 allows physically proximate attackers to clone a tag and unlock a door. The lock accepts replayed data captured from an authorized NFC tag because the credential lacks encryption or a challenge-response check. Brief proximity to an original tag is sufficient to copy its data; presenting the clone grants physical access through the protected perimeter.
