CVE-2025-43286

Local sandbox escape via SharedFileList permissions

Published Sep 15, 2025 · Updated Sep 15, 2025

Sandbox escape in Apple macOS Sonoma before 14.8, Sequoia before 15.7, and Tahoe before 26 allows local users to escape an app sandbox. SharedFileList applies insufficient permission restrictions, but Apple has not disclosed the affected operation or how crafted app input reaches it. Execution of a locally installed sandboxed app is required; escape removes that app's sandbox boundary, while no independent root privilege is reported.
