LINE client for iOS versions prior to 26.3.0 contains a vulnerability in the in-app browser where opening a crafted web page can repeatedly trigger OS-level dialogs due to insufficient safeguards when handling arbitrary URL schemes, potentially causing the iOS device to become temporarily inoperable.

LINE client for iOS prior to 15.19 allows UI spoofing due to inconsistencies between the navigation state and the in-app browser's user interface, which could create confusion about the trust context of displayed pages or interactive elements under specific conditions.

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.

The in-app browser in LINE client for iOS versions prior to 14.14 is vulnerable to address bar spoofing, which could allow attackers to execute malicious JavaScript within iframes while displaying trusted URLs, enabling phishing attacks through overlaid malicious content.

LINE client for Android versions prior to 14.20 contains a UI spoofing vulnerability in the in-app browser where the full-screen security Toast notification is not properly re-displayed when users return from another application, potentially allowing attackers to conduct phishing attacks by impersonating legitimate interfaces.

LINE client for Android versions from 13.8 to 15.5 is vulnerable to UI spoofing in the in-app browser where a specific layout could obscure the full-screen warning prompt, potentially allowing attackers to conduct phishing attacks.

Impact Successful exploitation of this vulnerability could allow an attacker to craft a malicious link that, when clicked by a victim, redirects them to a phishing website designed to mimic the legitimate Central Dogma login page. This could result in the compromise of user accounts and unauthorized access to the Central Dogma instance.

Patches This vulnerability is addressed and resolved in Central Dogma version 0.78.0. The server operators who run Central Dogma server with Shiro authentication are strongly encouraged to upgrade to this version or later to mitigate the risk associated with the open redirect vulnerability.

Workarounds Implement AuthProvider to overrides webLoginService().

The in-app browser of LINE client for iOS versions below 14.9.0 contains a Universal XSS (UXSS) vulnerability. This vulnerability allows for cross-site scripting (XSS) where arbitrary JavaScript can be executed in the top frame from an embedded iframe on any displayed web site within the in-app browser. The in-app browser is usually opened by tapping on URLs contained in chat messages, and for the attack to be successful, the victim must trigger a click event on a malicious iframe. If an iframe embedded in any website can be controlled by an attacker, this vulnerability could be exploited to capture or alter content displayed in the top frame, as well as user session information. This vulnerability affects LINE client for iOS versions below 14.9.0 and does not affect other LINE clients such as LINE client for Android. Please update LINE client for iOS to version 14.9.0 or higher.

Impact

The SAML implementation provided by armeria-saml currently accepts unsigned SAML messages (assertions, logout requests, etc.) as they are, rather than rejecting them by default. As a result, an attacker can forge a SAML message to authenticate themselves, despite the fact that such an unsigned SAML message should be rejected.

Patches

The vulnerability has been patched in Armeria version 1.27.2. All users who rely on armeria-saml older than version 1.27.2 must upgrade to 1.27.2 or later.

Workarounds

There is no known workaround for this vulnerability.

Vulnerability Overview A vulnerability has been identified in Central Dogma versions prior to 0.64.1, allowing for the leakage of user sessions and subsequent authentication bypass. The issue stems from a Cross-Site Scripting (XSS) attack vector that targets the RelayState of Security Assertion Markup Language (SAML).

Impact Successful exploitation of this vulnerability enables malicious actors to leak user sessions, leading to the compromise of authentication mechanisms. This, in turn, can facilitate unauthorized access to sensitive resources.

Patches This vulnerability is addressed and resolved in Central Dogma version 0.64.1 Users are strongly encouraged to upgrade to this version or later to mitigate the risk associated with the authentication bypass.

Workarounds No viable workarounds are currently available for this vulnerability. It is recommended to apply the provided patch promptly.
