Apple released updates for iOS/iPadOS, MacOS, TVOS, and WatchOS. This significant update fixes 39 vulnerabilities. Many affect multiple operating systems. One vulnerability in WebKit is already being exploited. Please consider the table below "experimental," as we still try to figure out how to correctly parse and rank the Apple updates.

This update will also enable end-to-end encryption for some iCloud data, like backups. It should be obvious that once enabled, and your data will be lost if you lose access to your devices or iCloud credentials. During the setup process, Apple does allow you to setup a recovery contact, essentially a trusted person that will be able to authenticate you during password recovery.
