With macOS 14.2 still in beta, Apple has released macOS Sonoma 14.1.2 with a pair of critical security Safari updates. Apple only says 14.1.2 includes “important bug fixes and security updates,” but its security update page describes two patches for WebKit flaws that “may have been exploited.”
The two WebKit flaws, which were also patched in iOS and iPadOS with 17.1.2:
