The tech behemoth advises everyone to download iOS 18.3.2 immediately in anticipation of the April release of the iOS 18.4 version. On March 11, the Apple announced that iOS 18.3.2 fixed an issue with streaming playback.

Apple’s release notes state that iOS 18.3.2 fixes a WebKit security flaw. Safari uses the company’s own web browser engine. Apple said that the Web material sandbox might be breached by maliciously created material.
A sandbox is more than simply fancy code for web developers. Programs, code, and other files can be launched in this isolated virtual environment to observe their behavior. The cybersecurity firm Proofpoint claims that “Browsers have their own sandboxes to separate malicious applications that run on the web from accessing local machine resources.” It gives your device an additional degree of security, and if online content manages to get past the sandbox, it may be able to access the data on your device.
According to Apple, this problem may have been exploited against particular users of iOS versions earlier than 17.2, and the most recent release provides a “supplementary fix.” Even if you may not have iOS 17.2 or be the target, you should still download the update right now to make sure your data and you are as protected as possible.
It is uncommon for Apple to send two security patches about a month apart, however the firm sometimes releases security fixes like this in between other, more feature-rich versions. On February 10, Apple launched iOS 18.3.1.
and same version also fixed a security flaw that, according to the corporation, may have been deliberately utilized against specific people.
These two upgrades vary only in that iOS 18.3.1 fixed a vulnerability that would have let someone physically connect to your iPhone and view your data. Therefore, in order to take advantage of that vulnerability prior to the upgrade, someone would need to be close to you. However, the most recent version fixes a vulnerability that may be used from thousands of kilometers away via the internet. Installing iOS 18.3.2 should shield you from this most recent danger.
