CVE-2025-43330

Local sandbox escape through undisclosed ATS flaw

Published Sep 15, 2025 · Updated Sep 15, 2025

Sandbox escape in ATS in Apple macOS Sequoia before 15.7 and Tahoe before 26 allows local users to escape an app sandbox. Apple states that the vulnerable ATS code was removed but has not disclosed the code path or operation that crosses the sandbox boundary. Exploitation requires a user to run an app locally; successful abuse lets that app act outside its assigned sandbox, with no reported availability impact.
