Missing encryption in the NFC tags of the Flient Smart Door Lock v1.0 allows attackers to create a cloned tag via brief physical proximity to the original tags, which results in an attacker gaining access to the perimeter.

Flient Smart Door Lock v1.0 is vulnerable to Use of Default Credentials. Due to default credentials on a debug interface, in combination with certain design choices, an attacker can unlock the Flient Smart Door Lock by replacing the fingerprint that is stored on the scanner.
