APPLE PATCHES TWO ZERO-DAY FLAWS USED IN TARGETED ATTACKS
Apple’s latest security updates affect iPhone, iPad, Mac, Apple Watch and Apple TV, so now is the time to check every device you own.(iStock)
What is CVE-2026-20700 and why it matters
CVE-2026-20700 is a memory corruption vulnerability affecting:
- iOS 26.3
- iPadOS 26.3
- macOS Tahoe 26.3
- watchOS 26.3
- tvOS 26.3
- visionOS 26.3
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.
Which devices need updating?
Here is a breakdown of the available updates:
- iOS 26.3 and iPadOS 26.3for iPhone 11 and later, plus newer iPads
- iOS 18.7.5 and iPadOS 18.7.5for iPhone XS, XS Max, XR and iPad 7th generation
- macOS Tahoe 26.3, Sequoia 15.7.4, Sonoma 14.8.4
- tvOS 26.3for Apple TV HD and Apple TV 4K
- watchOS 26.3for Apple Watch Series 6 and later
- visionOS 26.3for Apple Vision Pro
- Safari 26.3for supported macOS versions
If your device qualifies, update it as soon as possible.
Why this update deserves attention
Security updatescan 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.
