CVE-2025-30463

Sensitive data disclosure via insufficient container restrictions

Published Mar 31, 2025 · Updated Apr 2, 2026

Information disclosure in Handoff in iOS and iPadOS before 18.4 and macOS before 15.4 allows local users to run apps that access sensitive user data. The Handoff component fails to enforce the intended restriction on an app's access to data containers, allowing data to cross a protected boundary. Exploitation requires a locally run app and user interaction; the published impact is limited to confidentiality, with no data modification or service interruption.
