CVE-2022-46692

What it actually does

Logic flaw in state management allows processing of malicious web content to bypass Same Origin Policy checks, enabling unauthorized cross-origin access to resources.

Why it matters to the business

Attackers may steal sensitive data or perform unauthorized actions within web applications, increasing risk of data breaches and compliance violations; widespread browser usage amplifies exposure across organizations.

How an attack unfolds

An attacker crafts malicious web content exploiting the state management issue in WebKit; when a victim processes the content in a vulnerable browser version, the Same Origin Policy is bypassed allowing cross-origin data access. Threat actors associated with Apple product vulnerabilities have been linked to similar issues.

How to fix it

Update affected Apple products to fixed versions: Safari 16.2, tvOS 16.2, iCloud for Windows 14.1, iOS 15.7.2, iPadOS 15.7.2, macOS Ventura 13.1, iOS 16.2, iPadOS 16.2, watchOS 9.2. For vim/vim (GIT) environments referenced in package data, apply the commit e1d720ee69755b7e74c41bbc8ba5af0a70d1fb5f.

How to confirm the fix worked

Verify browser and OS versions match or exceed the listed fixed releases; test with known proof-of-concept web content to confirm Same Origin Policy enforcement is restored; review update logs for successful patch application.

Typical attack path

1. Attacker hosts or delivers maliciously crafted web content via phishing or compromised sites
2. Victim visits the page using a vulnerable Apple browser or WebKit-based application
3. Malicious content triggers the logic flaw during rendering or state handling
4. Same Origin Policy is bypassed, enabling unauthorized cross-origin reads or actions
5. Attacker exfiltrates data or performs further attacks within the victim's session context

How to detect it

Review web proxy logs, browser history, and network traffic for unusual cross-origin requests originating from untrusted domains; look for artifacts related to WebKit rendering processes handling suspicious content. Correlate with known threat actor patterns targeting Apple products.

What your security team should do

• Prioritize patching all Apple devices and browsers to the specified fixed versions immediately due to public disclosure over 1400 days ago
• Monitor EPSS trend and threat actor mentions for any increase in exploitation likelihood
• Implement content security policies and web isolation where feasible as defense-in-depth
• Audit downstream dependents and ecosystem usage for any lingering vulnerable instances
