What iOS 18.3.2 Fixes
iOS 18.3.2 and iPadOS 18.3.2, released March 11, 2025, fixes 1 vulnerability in 1 part of the system, according to Apple's security advisory.
Apple says one of these flaws — CVE-2025-24201 — may already have been exploited. That makes iOS 18.3.2 an update to install now rather than at the weekend.
It has since been superseded: the newest security release for iOS 18 is iOS 18.7.11 and iPadOS 18.7.11, from October 26, 2026, which includes these fixes.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.
Exploited Before the Fix
Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. This one is the reason to update today.

WebKit Exploited
Maliciously crafted web content may be able to break out of Web Content sandbox. This is a supplementary fix for an attack that was blocked in iOS 17.2. (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 17.2.)
An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions.
CVE-2025-24201
Which Devices Get iOS 18.3.2
Apple lists iOS 18.3.2 and iPadOS 18.3.2 for: iPhone XS and later, iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later.
How to Install iOS 18.3.2
On the iPhone, open Settings → General → Software Update. If more than one update is offered, the one with the higher version number is the current release; the other is for people who want to stay on the previous major version.
Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past iOS 18.3.2 there is nothing to do.
