Unauthorized local-network access via insufficient sandbox restrictions
Published Jul 29, 2025 · Updated Apr 2, 2026
Improper access control in Notes on Apple macOS allows local users to gain unauthorized access to the Local Network from a sandboxed app. The Notes sandbox applies insufficient local-network restrictions in Ventura before 13.7.7, Sonoma before 14.7.7, and Sequoia before 15.6. Execution of a local app is required; Apple does not disclose which Local Network services become reachable or what data they expose.
