Update your iPhone, iPad and Mac! New patch fixes nasty Safari issue

You’d like to think your browser prioritizes privacy. Unfortunately, sometimes our search providers let us down. Tap or click here to take a free, fast test that reveals how much private data our browser is leaking.

Last week, security researchers discovered that Apple’s Safari browser could leak your data to websites you visit. It all comes down to an implementation bug in IndexedDB, designed to hold user data.

Put simply, the bug lets websites see databases they shouldn’t. It also lets them search those databases for information like your browsing history, personal data and even your Google avatar. Luckily, Apple released a new update that fixes this privacy-endangering bug.

Patch the bug ASAP

Don’t wait to update. There’s a lot of personal information at risk. Not only is this bug an invasion of your privacy, but it also lets hackers see your browsing activity in real-time.

If you want to go into the weeds and get a technical understanding of how this works, check out this short video from FingerprintJS, the folks who blew the whistle on Jan. 14.

Fun fact: Someone reported the issue to the WebKit Bug Tracker on Nov. 28, 2021. Apple didn’t take action until Jan. 16 — after FingerprintJS shone a spotlight on the issue. (How curious.)

You can even run a quick test to see the problem in action

Head to Safari Leaks and see if the site can grab your Google User ID. You can even check out one of its test websites in a new tab. Return to the site and you’ll see that browsing history. It can be creepy to see the surveillance in real-time.

Typically, this shouldn’t be possible. When Safari is working correctly, Safari Leaks would have no way to find this information. That’s because sites are only supposed to access data from their databases. (Or to be super technical, databases its domain created.)

  • iPhone: iOS 15.3
