CVE-2025-43313

Sensitive user data disclosure through CoreServices logic flaw

Published Oct 15, 2025 · Updated Apr 2, 2026

Information disclosure in Apple macOS allows local users to access sensitive user data through an app running on the same Mac. Apple identifies the affected locus as CoreServices but has not published the flawed logic or the restrictions it applied incorrectly. Exploitation requires user interaction with a local app; the reported consequence is sensitive-data access, with no integrity or availability impact.
