Apple has issued a warning to its users after a serious vulnerability in its Safari browser was discovered. This opens iPhones and iPads to possible cyberattacks.

According to Fox News, the vulnerabilities affect WebKit, the browser engine that powers Apple’s Safari on its iOS software.

The identified issues made devices susceptible to hacking, potentially leading to the theft of sensitive information such as passwords and financial data.

It is rare for Apple to publicly warn about the vulnerability of its products to cyberattacks, and issuing such a warning should alert users to the seriousness of the threat.

The company has disclosed that the issues were discovered by its own team, along with Google’s Threat Analysis Group.

Apple has launched two iOS updates to fix these problems and has urged its users to update their devices to iOS 26.2 as a mitigation against the attacks. However, the same Fox News report from earlier indicates that only 50% of users have updated their devices.

The impacted devices include the iPhone 11 and later models, several generations of the iPad Pro, and the iPad Air starting with the third generation. For the iPad, it is from the eighth generation onward; for the iPad Mini, it is the fifth generation onward.

On its support page, Apple has advised that: “Keeping your software up to date is one of the most important things you can do to maintain your Apple product’s security.”
