CVE-2025-43261

Sandbox escape via File Bookmark logic error

Published Jul 29, 2025 · Updated Apr 2, 2026

A logic error in File Bookmark in Apple macOS allows local users to escape an app sandbox by running a sandboxed app. File Bookmark applies inadequate logic checks during bookmark handling, but Apple has not disclosed the specific operation or input that bypasses sandbox enforcement. Execution of a sandboxed local app is required; affected releases are macOS Ventura before 13.7.7, Sonoma before 14.7.7, and Sequoia before 15.6, and the disclosed consequence is escape from the app sandbox.
