Sensitive user data access via TCC permissions flaw
Published Mar 25, 2026 · Updated Mar 25, 2026
Improper access control in Apple macOS TCC before 14.8.5, 15.7.5, or 26.4 allows local users to read sensitive user data through an app. Apple identifies a permissions issue in TCC and says vulnerable code was removed, but it does not disclose the code path or failed permission check. Exploitation requires an app to run on the Mac; the reported consequence is disclosure of sensitive user data, with no reported data modification or service interruption.
