DescriptionCVE.org

A path handling issue was addressed with improved validation. This issue is fixed in Safari 26.5.2, iOS 26.5.2 and iPadOS 26.5.2, macOS Tahoe 26.5.2. Processing maliciously crafted web content may disclose sensitive user information.

AnalysisAI

Path traversal (CWE-22) in Apple's WebKit-based browser engine exposes sensitive user information when processing maliciously crafted web content in Safari, iOS, iPadOS, and macOS Tahoe prior to version 26.5.2. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms that an unauthenticated remote attacker needs only to induce a user to visit a malicious page, with no authentication or elevated privileges required. Apple has released fixes across all three platforms; no public exploit or CISA KEV listing has been identified at time of analysis.

Technical ContextAI

The root cause is CWE-22 (Improper Limitation of a Pathname to a Restricted Directory - Path Traversal), meaning the WebKit engine failed to adequately sanitize or validate path components when processing web content, allowing traversal outside the intended directory scope. This class of flaw in a browser context typically manifests in file URL handling, resource loading, or local storage access APIs where attacker-controlled path strings bypass normalization checks. CPE strings confirm the affected surface spans cpe:2.3:a:apple:safari, cpe:2.3:a:apple:ios_and_ipados, and cpe:2.3:a:apple:macos - all sharing the same underlying WebKit engine. Critically, on iOS and iPadOS, all third-party browsers are mandated to use WebKit, meaning the vulnerable code path is present in every browser on those platforms, not just Safari.app.

RemediationAI

Vendor-released patch available: update to Safari 26.5.2, iOS 26.5.2, iPadOS 26.5.2, or macOS Tahoe 26.5.2 immediately via Apple's standard update channels (Settings > General > Software Update on iOS/iPadOS; System Settings > General > Software Update on macOS). Apple advisory references: https://support.apple.com/en-us/127594, https://support.apple.com/en-us/127595, https://support.apple.com/en-us/127685. If immediate patching is not feasible on macOS, disabling JavaScript execution or using Safari's 'Fraudulent Website Warning' and content blocking extensions may reduce attack surface, though these are imperfect compensating controls that degrade browsing functionality. On iOS and iPadOS, switching to a third-party browser does NOT mitigate the vulnerability because all browsers on those platforms are required to use WebKit - system-level patching is the only effective remediation.
