CVE-2023-42937

Sensitive data disclosure via inadequate log redaction

Published Jan 23, 2024 · Updated Nov 4, 2025

Information disclosure in Apple Accessibility on affected iOS, iPadOS, macOS, and watchOS releases allows local users to read sensitive user data. Accessibility log-entry handling fails to redact private data adequately before records become accessible to an app. Local code execution as an app and user interaction are required; the disclosed consequence is limited to reading sensitive user data.
