Apple has released iOS 18.3.2, urging all users to download the update immediately to patch a serious security vulnerability. While the company is set to launch iOS 18.4 in April, this interim update focuses on fixing a streaming playback bug and, more importantly, addressing a major WebKit security flaw.
iOS 18.3.2, released on March 11, fixes an issue in WebKit, Apple’s internet browser engine used in Safari. The vulnerability allowed maliciously crafted web content to break out of the Web Content sandbox, potentially exposing users’ data. Apple warned that this flaw may have been actively exploited in a “highly sophisticated attack,” making immediate action crucial for all users.
How to Download iOS 18.3.2
To update your iPhone, follow these steps:
- Open Settings
- Go to General > Software Update
- Tap Update Now and follow the on-screen prompts
The sandbox in WebKit is designed to isolate malicious applications from accessing your device’s local resources. If compromised, attackers could potentially gain unauthorized access to sensitive data. Apple noted that previous versions of iOS before 17.2 were the main targets of this attack, but all users should install the update to ensure maximum security.
Apple also released iOS 18.3.1 on February 10, which addressed a separate vulnerability that could have allowed someone to physically connect to an iPhone and access data. Unlike that issue, iOS 18.3.2 fixes a remote exploit, meaning attackers could carry out the attack over the internet from anywhere in the world.
While Apple frequently rolls out security updates between major feature releases, two updates in quick succession highlight the severity of these vulnerabilities. Even if you don’t believe you were a target, downloading iOS 18.3.2 ensures the highest level of security for your device and personal data.
