Apple has released two new minor updates for iOS and watchOS devices. The company recommends that all users download iOS 14.4.2 and watchOS 7.3.3 as soon as possible. Like iOS 14.4.1 and macOS 11.2.3 before them, they fix a security flaw.
In one Support page identified by MacRumors, Apple claims that the vulnerability allowed malicious websites to perform cross-site scripting. It is an exploit that allows someone to get information from other web pages that you have opened on your device. Apple notes that it has received at least one report of someone taking advantage of the vulnerability in the wild. As always, you can manually start downloading an update to your iPhone by going to the Settings menu, tapping on “General,” then “Software Update.”
