CVE-2023-32444

Sandbox escape via undisclosed NSSpellChecker logic

Published Jul 28, 2023 · Updated Feb 13, 2025

Sandbox escape in NSSpellChecker in Apple macOS allows local users to circumvent sandbox restrictions from a sandboxed process. Apple identifies a validation-related logic error in NSSpellChecker but has not disclosed the faulty input, code path, or operation. Exploitation requires code already running inside an application sandbox on Big Sur before 11.7.9, Monterey before 12.6.8, or Ventura before 13.5; Apple reports no further consequence.
