Update: Apple has released an update for iOS fifteen to plug the security hole Safari .

A issues in Apple's Safari browser could reveal your recent web history and potentially your identity to any website you're using. And while Mac users can simply switch to another browser, iPad and iPhone users are out of luck, considering every alternative browser is besides impacted.

In a web log post published on Fri, browser fingerprinting service FingerprintJS explained the root of the problem, which affects Safari 15 for Mac and all versions on iOS 15 and iPadOS 15.

Information technology'south all related to the way WebKit implements a JavaScript API called IndexedDB. The bug, which was reported to WebKit on November 28, means that while a website should just be able to see IndexedDB databases information technology has created, it can actually see those generated by any websites during the user'southward browser session.

Every bit these entries are oftentimes unique to each website, that means that a site could figure out what other pages you're visiting in different tabs or windows. "A tab or window that runs in the background and continually queries the IndexedDB API for available databases can acquire what other websites a user visits in existent-time," the post explains. "Alternatively, websites can open whatever website in an iframe or popup window in order to trigger an IndexedDB-based leak for that specific site."

As some websites also create user-specific identifiers in the IndexedDB database names, that also means that bad actors could employ the exploit to figure out a seemingly anonymous browser's identity.

In the video below, FingerprintJS uses YouTube as an instance. One time logged in, the ID is changed to include a string that, with a footling legwork, can exist linked to a specific person:

IndexedDB databases can be accessed without any user input, the post adds, and enabling Private Browsing mode won't close the loophole either.

An analysis of Alexa's acme ane,000 most visited pages found that over 30 "collaborate with indexed databases direct on their homepage, without whatever additional user interaction or the need to authenticate."

That doesn't audio also bad, merely FingerprintJS believes that it's worse than it sounds. "Nosotros suspect this number to be significantly higher in existent-earth scenarios as websites tin collaborate with databases on subpages, afterward specific user actions, or on authenticated parts of the page," the mail continues.

Until a fix is issued, Mac users tin simply switch to another browser, but a similar solution isn't available for worried iPhone and iPad owners because Apple requires all browsers to use WebKit on its mobile platforms, significant Chrome and Firefox are also afflicted.

"I option may be to block all JavaScript by default and but allow it on sites that are trusted," the blog mail service explains, only it adds that this makes web browsing "inconvenient."

"The merely real protection is to update your browser or Os once the issue is resolved by Apple," the post concludes. "In the meantime, nosotros hope this article will heighten awareness of this issue."
