CVE-2023-32386

Local data disclosure via temporary-file handling

Published Jun 23, 2023 · Updated Dec 5, 2024

Privacy flaw in Contacts in Apple macOS before 11.7.7, 12.6.6, or 13.4 allows local users to observe unprotected user data. The Contacts component inadequately protects temporary files, exposing their contents to another app; Apple has not disclosed the file path or operation. A malicious app must execute locally in the user's context, and the reported consequence is observation of unprotected data without stated modification or code execution.
