Executive Summary

This is a logic issue in Apple operating systems where an app could potentially access sensitive user data due to insufficient validation. It affects macOS Sequoia, Sonoma, and Tahoe versions before the patched releases.

Detection Guidance

This vulnerability is specific to Apple macOS versions and involves unauthorized access to user-sensitive data. Detection requires checking installed macOS versions against the patched releases (Sequoia 15.7.8, Sonoma 14.8.8, Tahoe 26.6). Use system_profiler SPSoftwareDataType in Terminal to list macOS version details.

Impact Analysis
