Privacy

A vulnerability in macOS Mojave allows sandboxed applications to bypass sandbox restrictions and surreptitiously monitor user activities by registering for distributed notifications by name, circumventing intended privacy protections.

macOS QuickLook caches thumbnails and file paths of files, even those stored within encrypted containers or on removable USB devices, potentially revealing sensitive data to attackers with access to the running system.

macOS stores Signal message notifications in an unencrypted SQLite database, potentially exposing 'disappearing' messages even after they are deleted from the Signal application.
