CVE-2024-23231

Sensitive-data disclosure via insufficient log redaction

Published Mar 8, 2024 · Updated Apr 2, 2026

Information disclosure in Apple Share Sheet on affected iOS, iPadOS, macOS, and watchOS releases allows local apps to read sensitive data. Share Sheet writes user-sensitive content to log entries without sufficient private-data redaction. An app must execute locally and gain access to those entries; the documented consequence is data disclosure, not modification or service interruption.
