Sensitive data disclosure via improper file handling
Published Jan 23, 2024 · Updated Apr 2, 2026
Information disclosure in NSSpellChecker on affected Apple platforms allows local users to read sensitive user data through an app. NSSpellChecker handles files without adequate privacy protections, but Apple has not disclosed the specific file operation or data exposed. Exploitation requires locally running application code; the documented consequence is limited to reading sensitive user data, with no integrity or availability impact reported.
