DescriptionCVE.org

A logic issue was addressed with improved checks. 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. Visiting a maliciously crafted website may lead to a cross-site scripting attack.

AnalysisAI

A cross-site scripting (XSS) vulnerability exists in Apple's Safari browser and iOS/iPadOS operating systems due to insufficient input validation in website content handling. An attacker can craft a malicious website that, when visited by a user, executes arbitrary JavaScript in the context of the victim's browser, potentially stealing credentials, session tokens, or performing actions on behalf of the user. Apple has released patches across Safari 26.4, iOS 18.7.7, iPadOS 18.7.7, iOS 26.4, iPadOS 26.4, and macOS Tahoe 26.4 to address this logic flaw, though no CVSS score, EPSS data, or KEV status has been publicly disclosed, suggesting this may be a proactive disclosure rather than an actively exploited vulnerability.

Technical ContextAI

The vulnerability is rooted in a logic issue within Safari's content security and input sanitization mechanisms, affecting the rendering engine used across Apple's ecosystem. Safari (cpe:2.3:a:apple:safari:*:*:*:*:*:*:*:*), iOS and iPadOS (cpe:2.3:a:apple:ios_and_ipados:*:*:*:*:*:*:*:*), and macOS (cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*) all share WebKit rendering technology, making them collectively vulnerable. While no specific CWE classification is provided in the advisory, the XSS attack vector indicates a weakness in output encoding or filter bypass logic—typically CWE-79 (Improper Neutralization of Input During Web Page Generation). The flaw allows maliciously crafted HTML or JavaScript to bypass Safari's existing XSS protections, suggesting a logic gap rather than a complete absence of controls.

RemediationAI

Immediately update Safari to version 26.4 or later, iOS to version 18.7.7 or 26.4 or later, iPadOS to version 18.7.7 or 26.4 or later, and macOS to Tahoe 26.4 or later via Apple's Software Update mechanism. For users unable to patch immediately, disable JavaScript execution in Safari preferences as a temporary mitigation, though this will degrade website functionality. Additionally, users should avoid visiting untrusted or suspicious websites pending patch deployment. Enterprise administrators should leverage Mobile Device Management (MDM) to enforce automatic updates across iOS and iPadOS devices. Refer to the official Apple security advisories at https://support.apple.com/en-us/126792 through 126800 for detailed patch availability and deployment timelines.
