Apple says that both new software updates include security fixes that are absolutely worth installing. One of the fixes relates to a WebKit issue that the company notes could already have been actively exploited by bad actors.
Update time
The release notes(opens in new tab) for macOS Ventura 13.2.1 and iOS 16.3.1 mention a WebKit vulnerability alongside other issues relating to the Kernel and, in the case of the Mac, Shortcuts. But it's that WebKit issue that is most concerning.
"Processing maliciously crafted web content may lead to arbitrary code execution," Apple's release notes start out before adding the kicker — "Apple is aware of a report that this issue may have been actively exploited."
That's a vitally important part because it means that someone somewhere is already using this exploit to run arbitrary code. And while it's unlikely that most people reading this are targets for those kinds of people, an abundance of caution is always wise when it comes to iPhone and Mac security.
Apple notes that anyone with a compatible iPhone (or iPad, for that matter) should update now, whether that's an iPhone 8 or Apple's latest and best iPhones, including the iPhone 14 Pro. The same goes for the Mac, too.
We'd always suggest installing Apple's new updates regardless of whether security fixes are included, but in this case, it really is a no-brainer. Those with an iPhone can head into the Settings app to begin the update process, while the macOS Ventura update mechanism can be found in the System Settings app.
