Apple has rolled out its latest update, iOS 18.4, bringing not only exciting new features but also a critical warning for all iPhone users to update immediately. This update addresses a staggering 62 security vulnerabilities, some of which are rated as highly severe.

Apple has chosen to keep the specifics of the vulnerabilities under wraps for now, aiming to shield users from potential exploits before they become widespread. Among the key fixes is a patch for a vulnerability in WebKit, the underlying engine for the Safari browser, as well as crucial updates to the iPhone's Kernel that could be targeted by malicious software.

One significant flaw, identified as CVE-2025-30432, allows attackers to attempt passcode entries on a locked iPhone, possibly leading to unauthorized access. Another issue, cataloged as CVE-2025-24208, could expose users to cross-site scripting attacks, where an attacker injects harmful scripts into seemingly trustworthy websites.

Critical Context: Recent Security Breaches

This update follows closely on the heels of Apple's urgent iOS 18.3.2 update, released less than a month ago, which addressed an actively exploited vulnerability. Such rapid updates reflect Apple’s heightened focus on user security and the constant threats lurking in the digital landscape.

The majority of the patched vulnerabilities relate to WebKit, indicating an ongoing trend where attackers are increasingly targeting web frameworks. Adam Boynton, a senior security strategist, noted that iOS 18.4's fixes are crucial as they secure both the Core Media framework and the Kernel—components essential for managing device software and hardware interactions.

Another notable highlight from iOS 18.4 is a new location setting called "Improve Location Accuracy," which enhances GPS functionality, but has now been enabled by default. This feature could potentially raise privacy concerns, prompting users to review and manage their settings.

For those worried about the number of vulnerabilities fixed in the latest update, Sean Wright, a security expert, reassured users that the timely nature of these updates shows Apple's commitment to security.
