CVE-2023-23506

Sensitive-data disclosure via insufficient libxpc validation

Published Feb 27, 2023 · Updated Mar 11, 2025

Incorrect authorization in libxpc in Apple macOS before 13.2 allows local users to access user-sensitive data through a malicious app. Libxpc insufficiently validates an app's request for protected user data; Apple has not disclosed the specific request or failed authorization check. Successful exploitation requires a user to launch the app, and the documented consequence is data disclosure without modification or service interruption.
