CVE-2025-43329

Local sandbox escape via insufficient permission restrictions

Published Sep 15, 2025 · Updated Sep 15, 2025

Missing authorization in Apple's Sandbox component before 26 allows local users to make a sandboxed app escape its restrictions. Apple states that Sandbox enforced insufficient permission restrictions but has not disclosed the affected API, policy rule, or authorization check. Exploitation requires local execution of an app and removes its sandbox boundary, allowing operations that the sandbox should deny.
