** DISPUTED ** An issue was discovered in the LINE jp.naver.line application 8.8.0 for iOS.

In other words, an attacker could authenticate with an arbitrary fingerprint. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes iOS devices on which a jailbreak has occurred.
