MEDIUM 5.3

DescriptionCVE.org

A parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in macOS Tahoe 26.4. An app may be able to access sensitive user data.

AnalysisAI

Improper path validation in Apple macOS Tahoe allows unauthenticated remote attackers to read sensitive user data through directory path traversal. The vulnerability requires no user interaction and affects systems prior to macOS Tahoe 26.4. No patch is currently available for this medium-severity issue.

Technical ContextAI

The vulnerability stems from insufficient path validation in macOS's directory path handling mechanisms, likely affecting file system access control layers used by applications. This represents a classic path traversal or improper input validation weakness (conceptually aligned with CWE-22 Improper Limitation of a Pathname to a Restricted Directory, though CWE details are not formally declared). The affected technology is the core macOS operating system itself (CPE: cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*), meaning the parsing logic resides in macOS kernel or system frameworks that mediate inter-process access to protected user directories. The lack of proper validation allows applications to manipulate directory path constructs to bypass sandboxing or access control boundaries and reach sensitive user data repositories.

RemediationAI

Upgrade to macOS Tahoe 26.4 or later immediately, following Apple's standard software update process through System Preferences or Software Update. Users unable to patch immediately should restrict the execution of untrusted applications and review application permissions via System Preferences > Security & Privacy, limiting app access to sensitive directories where possible. Additionally, organizations can deploy additional endpoint detection and response (EDR) tools to monitor for suspicious directory access patterns or privilege escalation attempts. Refer to Apple's official advisory at https://support.apple.com/en-us/126794 for patch availability and deployment timelines.
