Microsoft discovered a vulnerability in macOS that can let attackers bypass application execution restrictions imposed by Apple's Gatekeeper security mechanism.
The bug, dubbed "Achilles," could be used by malware and other threats to gain initial access to a device and increase the success rate of attacks on macOS.
Apple addressed the bug in macOS 13 (Ventura), macOS 12.6.2 (Monterey), and macOS 1.7.2 (Big Sur).
