Local sensitive data disclosure

Published May 26, 2026 · Updated May 26, 2026

Improper authorization in Apple macOS CoreServices before 14.8, 15.7, and 26 allows local users to read sensitive user data. CoreServices performs an undisclosed validation operation incorrectly, and Apple has not identified the input, code path, or authorization boundary involved. Exploitation requires a malicious app running with low local privileges; the reported impact is limited to unauthorized disclosure, with no integrity or availability impact.
