CVE-2025-43399

Protected user-data exposure via inadequate redaction

Published Nov 4, 2025 · Updated Nov 4, 2025

Information disclosure in Siri in Apple macOS Sequoia before 15.7.2 and Tahoe before 26.1 allows attackers to read protected user data. Siri fails to fully redact sensitive information before making it accessible to applications, but Apple has not disclosed the affected data flow or API. Exploitation requires an app to reach the vulnerable Siri behavior; the reported consequence is read-only disclosure, with no integrity or availability impact.
