Exploitability

CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This is a path traversal vulnerability where an app could break out of its sandbox due to insufficient input validation. This allows the app to access files or directories outside its intended restricted area.

Detection Guidance

This CVE describes a path traversal issue in macOS fixed in specific versions. Detection requires checking if your macOS version is below the patched releases (Sequoia 15.7.8, Sonoma 14.8.8, Tahoe 26.6). Use the command 'sw_vers' to check your macOS version.

Impact Analysis

An attacker could exploit this to access sensitive files or system resources on your device. This may lead to unauthorized data exposure or manipulation if a malicious app is installed.

Compliance Impact

The provided CVE data does not specify direct impacts on compliance with standards like GDPR or HIPAA. The vulnerability involves a path traversal issue allowing sandbox escape, which could potentially lead to unauthorized data access. However, without explicit details on data exposure or regulatory implications, its compliance impact remains unclear.

Mitigation Strategies

Update to the latest patched versions of macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6 to address the path traversal issue and sandbox escape vulnerability.
