Executive Summary

A file quarantine bypass vulnerability in macOS allows an app to bypass Gatekeeper checks, which are security mechanisms designed to verify downloaded files before execution. This bypass could let malicious apps run without proper validation.

Detection Guidance

This vulnerability involves a file quarantine bypass in macOS versions prior to Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6. Check your macOS version using 'sw_vers' to confirm if your system is affected. If you suspect exposure, inspect downloaded files for unexpected execution or Gatekeeper bypass attempts.

Impact Analysis

This vulnerability could allow malicious software to execute on your system without being blocked by Gatekeeper, potentially leading to malware infections, data theft, or unauthorized access to your device.

Compliance Impact

This vulnerability allows an app to bypass Gatekeeper checks, which could enable unauthorized or malicious software to run on a system. This may impact compliance with standards like GDPR or HIPAA by increasing the risk of data breaches or unauthorized access to sensitive information.

Mitigation Strategies

Update to the latest versions of macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6 to address the file quarantine bypass issue.
