Apple has issued a critical security alert to all iPhone users, urging them to update their devices immediately following the discovery of multiple serious vulnerabilities. The tech giant's latest software patch, iOS 26.2, addresses a total of 27 security issues that could leave devices open to attack.
Sophisticated Attacks on Targeted Individuals
Among the flaws corrected is a particularly severe exploit within the WebKit browser engine, the technology that powers Safari. Apple confirmed that this vulnerability, tracked as CVE-2025-14174, may have already been used against specific individuals in what the company described as an 'extremely sophisticated attack'.
The exploit, which affected iPhones running software versions older than iOS 26, could allow attackers to execute arbitrary code on a victim's device simply by having them process malicious web content. Apple's policy is not to discuss security issues publicly until an investigation is complete and a fix is ready, which is why such warnings often seem to emerge suddenly.
How to Check and Install the Vital Update
For any user concerned about their device's safety, the first and most crucial step is to ensure their iPhone is running the latest software. As of 13 January 2026, this is iOS 26.2.
You can check for the update by following these simple steps:
- Open the Settings app on your iPhone.
- Tap on General.
- Select Software Update.
- If iOS 26.2 is available, tap Download and Install.
Apple strongly recommends backing up your device using iCloud or a computer before proceeding with any major software installation.
Which iPhones Are Eligible for the Update?
The iOS 26.2 update is available for a wide range of models, from the iPhone SE (2nd generation) right through to the latest iPhone 17 series, including all Pro, Pro Max, and Air variants. It also supports models from the iPhone 11, 12, 13, 14, 15, and 16 generations.
In its official guidance, Apple states plainly: 'Keeping your software up to date is one of the most important things you can do to maintain your Apple product's security.' This latest warning serves as a stark reminder that no device is invincible, and regular updates are a key defence in an increasingly complex digital landscape.
