DescriptionCVE.org

This issue was addressed through 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, tvOS 26.4, visionOS 26.4, watchOS 26.4. Processing maliciously crafted web content may prevent Content Security Policy from being enforced.

AnalysisAI

This vulnerability allows attackers to bypass Content Security Policy (CSP) enforcement in Apple's WebKit engine through maliciously crafted web content, affecting Safari and all Apple platforms including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. The vulnerability stems from improper state management during web content processing, enabling attackers to circumvent a critical security control that prevents injection attacks and unauthorized script execution. While no CVSS score or EPSS data is currently available, the broad platform impact across Apple's entire ecosystem and the fundamental nature of CSP bypass as an information disclosure vector indicate significant real-world risk.

Technical ContextAI

This vulnerability relates to WebKit's Content Security Policy implementation, which is a critical HTTP header-based security mechanism that restricts the sources from which content can be loaded and executed in web pages. The root cause involves improper state management (likely related to policy initialization, inheritance, or enforcement tracking across document lifecycle events) in how Safari and WebKit-based browsers process and maintain CSP directives when handling specially crafted web content. The affected products span Apple's entire platform portfolio via 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:tvos, cpe:2.3:a:apple:visionos, cpe:2.3:a:apple:watchos), indicating the vulnerability exists in a shared WebKit component that powers all these implementations. The classification as Information Disclosure suggests the bypass enables attackers to exfiltrate data that CSP would normally protect against.

RemediationAI

Immediately upgrade Safari to version 26.4 or later. For iOS and iPadOS users, install security updates 18.7.7 or 26.4 depending on device eligibility. macOS users should upgrade to Tahoe 26.4, while tvOS, visionOS, and watchOS users should update to version 26.4 respectively. Because this vulnerability affects core web content processing, all patches should be applied urgently to prevent CSP bypass exploitation. Until patches can be deployed, users should limit browsing to trusted websites and disable JavaScript execution in browser settings if feasible, though this significantly impacts web functionality. For enterprises, consider deploying web content filtering at network boundaries to block delivery of potentially malicious web content. All patching information and version-specific advisories are available at the Apple support URLs listed in the affected products section.
