A logic issue was addressed with improved state management. This issue is fixed in Safari 26.4, iOS 18.7.7 and iPadOS 18.7.7, iOS 26.4 and iPadOS 26.4, macOS Tahoe 26.4, visionOS 26.4. A malicious website may be able to access script message handlers intended for other origins.
AnalysisAI
A logic error in Apple's script message handler implementation allows malicious websites to access script message handlers intended for other origins, resulting in unauthorized cross-origin information disclosure. This vulnerability affects Safari 26.4 and earlier, iOS/iPadOS 18.7.7 and earlier, macOS Tahoe 26.4 and earlier, and visionOS 26.4 and earlier. An attacker can craft a malicious website that exploits improper state management in the message handler routing mechanism to intercept sensitive data intended for legitimate web applications, potentially exposing authentication tokens, user data, or other confidential information passed through script messaging interfaces.
Technical ContextAI
The vulnerability resides in Apple's WebKit engine, specifically in the script message handler subsystem that facilitates communication between web content and native application code. Script message handlers (WKScriptMessageHandler) are a documented API for bridging JavaScript in web pages with native Swift or Objective-C code. The root cause is classified as a logic error in state management—meaning the handler routing mechanism fails to properly maintain or validate the origin context when routing incoming messages. Rather than a traditional memory safety issue, this is a design flaw where the handler state does not correctly enforce same-origin policy constraints, allowing a malicious origin to read messages destined for a different origin. The affected CPE strings (cpe:2.3:a:apple:safari, cpe:2.3:a:apple:ios_and_ipados, cpe:2.3:a:apple:macos, cpe:2.3:a:apple:visionos) indicate the vulnerability spans Safari browser and all iOS, iPadOS, macOS, and visionOS platforms that share the common WebKit rendering engine.
RemediationAI
Immediately upgrade to Safari 26.4 or later, iOS/iPadOS 18.7.7 or later (or iOS/iPadOS 26.4 or later on supported devices), macOS Tahoe 26.4 or later, or visionOS 26.4 or later. These patches address the logic flaw in script message handler state management by improving validation of origin context before routing messages. Users should enable automatic updates in Settings > General > Software Update (iOS/iPadOS) or System Settings > General > Software Update (macOS) to ensure timely patching. Until patches can be applied, restrict web browsing to trusted websites only and disable JavaScript where feasible for non-essential browsing. Organizations managing Safari deployments should use Mobile Device Management (MDM) or enterprise deployment tools to enforce immediate patching across all endpoints. Refer to Apple's official security advisories at https://support.apple.com/en-us/126792 (Safari), https://support.apple.com/en-us/126793 (iOS), https://support.apple.com/en-us/126794 (iPadOS), https://support.apple.com/en-us/126799 (macOS), and https://support.apple.com/en-us/126800 (visionOS) for version-specific guidance.
