Don't ignore Apple's urgent security update

18 Feb 2026 By foxnews

If you use an iPhone, iPad, Mac, Apple Watch or Apple TV, listen up. Apple has released a major security update to fix a zero-day vulnerability, which is a security hole that hackers discover and exploit before the company has a chance to fix it.

Attackers were already using it in targeted attacks. In other words, this was not just a possibility. It was happening.

The flaw, tracked as CVE-2026-20700, affects multiple Apple operating systems. If you have delayed updates lately, this is one you should not ignore.

If you own an Android or Windows PC, this is also a good reminder to check for updates.

APPLE PATCHES TWO ZERO-DAY FLAWS USED IN TARGETED ATTACKS

CVE-2026-20700 is a memory corruption vulnerability affecting:

In simple terms, this bug could allow an attacker to run arbitrary code on your device. That opens the door to spyware, hidden backdoors or silent takeovers without obvious warning signs. Apple says this vulnerability was used as part of an infection chain combined with two previously patched flaws against devices running older versions of iOS. Those earlier bugs were fixed in December 2025. Devices that skipped those updates remained exposed. This is how many real attacks unfold. Hackers chain vulnerabilities together and quietly move in.

Here is a breakdown of the available updates:

If your device qualifies, update it as soon as possible.

Security updates can feel routine. Many of us see the notification and decide to deal with it later. This time is different. Apple confirmed the flaw was actively exploited. That means attackers already know how to use it. Running older software gives them a window of opportunity. Updating closes that window.

Updating takes only a few minutes.

Keep your device connected to Wi-Fi and power during the process.

Your Mac may restart during the process. Keep it plugged in and connected to the internet until the update finishes.

Your Watch will restart during the update.

Stay connected to power and Wi Fi until the update completes.

Safari updates are included with macOS updates.

If Safari appears separately, click Update Now and restart your Mac.

Installing this update is the most important step. Still, there are additional habits that strengthen your protection.

Cybercriminals rely on hesitation. They count on us assuming we will get to the update later.

Apple moved fast to fix this vulnerability, and that is reassuring. Now it is up to us to do our part. I get it. Updates interrupt your day. They force a restart. They rarely feel urgent. But here is the thing. Installing updates is still the simplest and most effective way to protect your device from active threats. A few minutes now can prevent a serious security problem later.
