Apple has issued a warning that a significant security flaw affects approximately 800 million iPhones, urging users to update to iOS 26.2 to mitigate critical vulnerabilities in Safari and WebKit.
Apple’s iPhone, the leading smartphone in the United States and widely used globally, is facing a serious security threat. Recent data indicates that a critical vulnerability could potentially impact around half of all iPhone users, leaving hundreds of millions of devices at risk.
Over the past few weeks, Apple has been alerting users to a significant security flaw that affects an estimated 800 million devices. This vulnerability stems from two critical issues identified in WebKit, the underlying engine that powers Safari and other browsers on iOS. According to Apple, these flaws have been exploited in sophisticated attacks targeting specific individuals, enabling malicious websites to execute harmful code on iPhones and iPads. This could allow attackers to gain control of the device, steal passwords, or access sensitive payment information simply by visiting a compromised site.
In response to this threat, Apple quickly released a software update to address the vulnerabilities. However, reports suggest that many users have yet to install the necessary update. Estimates indicate that approximately 50 percent of eligible users have not upgraded from iOS 18 to the latest version, iOS 26.2. This leaves a staggering number of devices vulnerable worldwide. According to data from StatCounter, the situation may be even more dire, with only about 20 percent of users having completed the update so far. As security details become public, the risk of exploitation increases significantly, as attackers are aware of the vulnerabilities to target.
Apple has specified that certain devices are affected by this vulnerability if they remain unupdated. Users are strongly encouraged to check their devices and ensure they have installed the latest software to protect against potential attacks.
There is no simple setting or browsing habit that can mitigate this issue; the vulnerability is embedded deep within the browser engine. Security experts emphasize that the only effective defense is to install the latest software update. Apple has also discontinued offering a security-only update for users who wish to remain on iOS 18. Unless a device cannot support iOS 26, the fix is only available through the latest versions of iOS 26.2 and iPadOS 26.2.
Updating is generally a straightforward process. If automatic updates are enabled, users may already have the fix installed. For those who need to update manually, the following steps are recommended: ensure the device is connected to Wi-Fi and has sufficient battery life or is plugged in for the update process.
While keeping your iPhone updated is crucial, it should not be the sole line of defense against threats. Utilizing strong antivirus software can provide an additional layer of protection by scanning for malicious links, blocking risky websites, and alerting users to suspicious activity before any damage occurs. This is particularly important given that many attacks exploit compromised websites or hidden browser vulnerabilities. Security software can help identify threats that may slip through and offer greater visibility into device activity.
Think of antivirus software as a backup protection measure. Software updates close known vulnerabilities, while robust antivirus tools help guard against emerging threats.
Apple’s use of the term “extremely sophisticated” in describing the threat underscores the seriousness of the situation. This flaw illustrates how even trusted browsers can become pathways for attacks when updates are delayed. Users who rely on their iPhones for banking, shopping, or work should treat this update as urgent.
As the landscape of cybersecurity continues to evolve, users are left to consider how long they typically wait before installing major iPhone updates. Is that delay worth the risk? Feedback and insights can be shared at Cyberguy.com.
