CVE-2025-14022: Linecorp Line

Medium severity, CVSS 6.8. EPSS: 0.2% chance of exploitation in the next 30 days.

LINE client for iOS prior to 15.4 allows man-in-the-middle attacks due to improper SSL/TLS certificate validation in an integrated financial SDK. The SDK interfered with the application's network processing, causing server certificate verification to be disabled for a significant portion of network traffic, which could allow a network-adjacent attacker to intercept or modify encrypted communications.

Affected products

• Linecorp Line: before 15.4.0 (fixed in 15.4.0)
