Name of the Vulnerable Software and Affected Versions LINE client for iOS versions prior to 15.4

Description The application experiences man-in-the-middle attacks because of flawed SSL/TLS certificate validation within an integrated financial SDK.

This allows a network-based attacker to intercept or alter encrypted communications.
