CVE-2023-42936

Sensitive user-data disclosure via incomplete redaction

Published Mar 28, 2024 · Updated Nov 4, 2025

Information disclosure in affected Apple platforms allows local users to access sensitive user data through a locally executed app. The Sandbox component insufficiently redacts sensitive information before making it available to the app; Apple has not disclosed the specific data path. Exploitation requires user interaction to run the app, and the documented consequence is limited to reading user-sensitive data.
