  • The release patches a WebKit security vulnerability on macOS Catalina and Mojave.

Apple has patched a WebKit vulnerability that was affecting Safari on the Mac.

As reported by 9to5Mac, Apple has released Safari 14.1 for users running macOS Catalina and macOS Mojave. The update patches a security vulnerability with WebKit that was fixed earlier this week for users on iOS 14.5 and macOS Big Sur.

Earlier this week, Apple released iOS 14.5.1 and macOS Big Sur 11.3.1 with an important security update that fixed a serious WebKit exploit. Today the company released Safari 14.1 for users running macOS Catalina and macOS Mojave, which also fixes the exploit that had been being used for malicious web content.As Apple detailed earlier this week, the exploit found in WebKit had been exploited to execute arbitrary code on a user's device without consent.

While the updates to iOS and macOS Big Sur patched the issue for those users, Apple has now released Safari 14.1 to fix the vulnerability for users running older versions of macOS.
