Update to macOS Monterey Fixes Safari Leak

Update to macOS Monterey Fixes Safari Leak

Along with its release of iOS and iPadOS 15.3, watchOS 8.4, and more, Apple today began rolling out macOS Monterey 12.2 to all customers. The most notable fix in the update resolves an issue that let Safari leak sensitive information between web pages.

WebKit Storage Bug Caused Safari Leak

In the release notes, Apple points out a cross-origin issue in the IndexDB API. Identified as CVE-2022-22594 and reported by Martin Bajanik of FingerprintJS, the bug allowed websites to track sensitive user information across different sites.

According to Apple, improved input validation resolved the issue. Testers at 9to5Mac confirmed the bug no longer affects Safari on macOS as of the Release Candidate distributed last week.

Apple also patched three other security issues in WebKit. These include issues allowing maliciously crafted emails and web content allowing arbitrary code execution as well as entering with Content Security Policies.

Other Resolved Issues in macOS Monterey 12.2

The number of bugs fixed by macOS Monterey 12.2 is a fairly extensive list, so installing the update as soon as possible would be a great idea. Do so by going to System Preferences > Software Update and clicking Update Now. If it doesn’t appear right away, you may have to refresh Software Update to make it show up.
