Should you update to iOS 18.7.11?
Yes, today. iOS 18.7.11 is a security update Apple released on 26 Oct 2026 for iPhone and iPad. It fixes 3 security flaws.[1] One of them is already being used in attacks.
It is the newest iOS 18 release, so it’s the one to have.
Should you update?
Yes, today. One of the flaws it fixes is already being used in attacks. Every security update closes holes that become public the moment it ships, so the risk of staying on the old version only grows. Waiting a week to see if others hit problems is a common habit; with a security update it’s the wrong trade.
Is iOS 18.7.11 safe to install?
Yes. It’s Apple’s own security release, and updates rarely go wrong; a backup makes it painless if one does. The one unsafe way to get it is from a link: Apple never sends updates by email, text or pop-up, so install it only from Settings → General → Software Update.
18.7.11 or 27.2?
If your device can run iOS 27, Apple may offer two updates: iOS 18.7.11, which keeps you on iOS 18, and iOS 27.2 (163 security flaws), which moves you to iOS 27. Both close the same holes where they apply.
Not ready for iOS 27, because of an app you rely on or a look you prefer? Install iOS 18.7.11 and you’re just as safe for now. If your device can’t run iOS 27, iOS 18.7.11 is the one to install.
What it fixes
Apple lists 3 security flaws across 3 parts of iOS. For each, Apple says what an attacker could have done before the fix.[1]
| Part | Flaws | What an attacker could do |
|---|---|---|
| Audio | 1 | An app may be able to leak sensitive user information |
| CoreGraphics | 1 | Processing a maliciously crafted file may lead to arbitrary code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27. |
| CoreMedia | 1 | A malicious app may be able to access the camera without user permission |
Used in attacks
This fix closes a flaw that attackers were already using before the update came out, either on CISA’s list of flaws being used in attacks or in Apple’s own words.[2]
How to update, and how long it takes
It takes 15 to 45 minutes in all: a few minutes to download, then it prepares, installs and restarts, and you can’t use the iPhone or iPad while it installs.
- Back up first if you can.iCloud backup or your computer. Updates rarely go wrong, but a backup makes it painless if one does.
- Open Settings → General → Software Update.Your iPhone or iPad shows the newest version it can run. Tap or click Update Now, or Upgrade Now for a new major version.
- Leave it plugged in.It downloads, prepares and restarts. Expect 15 to 45 minutes.
- Turn on automatic updates.In the same place, under Automatic Updates, turn on both downloading and installing security responses and updates.
To check it worked: Settings → General → About shows the iOS version. It should say 18.7.11 or later.
Older devices
The same day, Apple released iOS 27.2 (163 security flaws) and iOS 26.7.2 (134 security flaws) for devices that stay on an older version. Each fixes the same holes where they apply.
