CVE-2025-14022

Traffic interception via disabled certificate verification

Published Dec 15, 2025 · Updated Dec 15, 2025

Improper certificate validation in LINE for iOS before 15.4 allows man-in-the-middle attackers to intercept or modify encrypted traffic. An integrated financial SDK interferes with the client's network processing and disables server certificate verification across a significant portion of its traffic. An attacker must control the network path; successful exploitation exposes traffic to disclosure or modification without authentication or user interaction.
