Gatekeeper bypass via insufficient quarantine checks
Published Jul 27, 2026 · Updated Jul 27, 2026
File quarantine bypass in Apple macOS Sonoma before 14.8.8, Sequoia before 15.7.8, and Tahoe before 26.6 allows local users to bypass Gatekeeper. DesktopServices applies insufficient checks during file-quarantine processing, but Apple has not disclosed the affected attribute, operation, or validation path. A locally launched app and user interaction are required; the documented consequence is Gatekeeper-check bypass without reported privilege escalation.
