The iPhone is the most widely used smartphone in the United States, boasting around 1.6 billion users globally. This extensive user base makes it a prime target for cybercriminals, underscoring the need for vigilance regarding device security.
Recently, Apple issued a warning to users about a significant security vulnerability found in the Safari browser. This flaw could potentially expose nearly half of all iPhone users to security risks, putting a vast number of devices in jeopardy. If your device is not updated, your personal information could be at risk.
Understanding the vulnerability in Safari
Last month, Apple identified two critical weaknesses in WebKit, the engine that powers Safari and other browsers on iOS. These vulnerabilities have been exploited in sophisticated attacks targeting specific individuals. Malicious websites can manipulate iPhones and iPads into executing harmful code, granting attackers access to sensitive data, including passwords and payment information. Simply visiting a compromised website could lead to serious consequences.
Immediate response from Apple
In light of this alarming discovery, Apple promptly released a fix as part of its latest software update. However, many users have yet to implement this critical update. Estimates suggest that around 50% of eligible users have not transitioned from iOS 18 to iOS 26, leaving approximately 800 million devices vulnerable worldwide. According to StatCounter, only about 20% of users have completed the update so far. Once security flaws become public knowledge, the risk of exploitation rises rapidly, as malicious actors know exactly what to target.
Devices at risk
Apple has stated that certain models are at an increased risk if users do not update their software. The following devices are affected:
- iPhone 11and all newer models
- iPad Pro 12.9-inch3rd generation and later
- iPad Pro 11-inch1st generation and later
- iPad Air3rd generation and later
- iPad8th generation and later
- iPad mini5th generation and later
If your device is on this list and remains outdated, it is susceptible to potential threats.
Why updating is crucial
It’s important to understand that there is no simple setting adjustment or browsing method that can mitigate this issue. The vulnerability is embedded within the browser engine, and security experts agree there is no workaround that significantly reduces the risk. The only reliable defense is to install the latest software update. Apple no longer provides security-only updates for users wishing to remain on iOS 18. If your device supports it, the fix is available exclusively through iOS 26.2 and iPadOS 26.2.
Steps to update your device
Updating your iPhone or iPad is a straightforward process, typically occurring without complications. If you have automatic updates enabled, the fix may already be applied. If you haven’t set that up, follow these simple steps:
- Open theSettingsapp on your iPhone.
- SelectGeneral.
- Tap onSoftware Update.
- Download and installiOS 26.2oriPadOS 26.2or later.
- Ensure your device is connected to Wi-Fi and has sufficient battery power or is plugged in.
Enhancing security with antivirus software
While keeping your iPhone updated is essential, it should not be your only line of defense. Using robust antivirus software provides an extra layer of security by scanning for malicious links, blocking risky websites, and alerting you to suspicious activity before it escalates. This is particularly important as attacks increasingly rely on compromised websites or hidden browser vulnerabilities. Think of antivirus software as a backup measure; while software updates seal known vulnerabilities, strong antivirus tools help protect against new threats that may arise.
Apple’s recent warnings highlight the urgency of timely software updates to safeguard users from vulnerabilities. If you frequently use your iPhone for banking, online shopping, or sensitive work tasks, consider updating your device as an urgent priority.
