New Microsoft Edge Update Addresses Major Security Issue

Microsoft continues to refine its browser experience, from testing a redesigned new tab page with dual sidebars to rolling out regular security patches. Speaking of security updates, the company has now released the first stable update for Microsoft Edge in 2026, focusing squarely on security and reliability.

The latest Edge patch fixes a Chromium vulnerability

As reported by Neowin, Microsoft pushed Edge version 143.0.3650.139 to desktop users, delivering fixes for multiple bugs and at least one serious security flaw.

The most important fix addresses a high-severity vulnerability tracked as CVE-2026-0628. The issue comes from a component in Chromium and could allow a malicious browser extension to inject scripts or HTML into privileged Edge pages under certain conditions.

While this sounds troubling, as a user, you would be in danger only if the attacker has somehow convinced you to install a malicious extension on your own. As long as you use trusted and reliable extensions, you should be okay.

Because the vulnerability affects core browser behavior, Microsoft urges users to update Edge as soon as possible to reduce exposure and maintain strong browser security. The patch follows a familiar pattern, with Microsoft rapidly incorporating Chromium security fixes into Edge builds.

Alongside security work, Microsoft continues to experiment with new features. The company currently tests Copilot integration inside Immersive Reader, while also streamlining the browser by removing older features Collections.

This update reinforces Microsoft’s ongoing approach with Edge: frequent security maintenance, steady feature experimentation, and gradual cleanup of legacy functionality.
