Microsoft updates Edge with fixes for a high-severity security vulnerability

The holiday season is now behind us, and Microsoft is returning to its normal operation mode. On January 9, Microsoft released the first preview build for Windows 11 in 2026, and now, Microsoft Edge is getting a fresh update as well. Version 143.0.3650.139 is now available for Edge on desktop, bringing users some bug fixes and security improvements.

The update does not contain much. The official changelog only says that there are "bug fixes" and a single fix for a Chromium security issue. The vulnerability in question is CVE-2026-0628. It is a high-severity bug that allows code injection via malicious extensions:

CVE-2026-0628: Insufficient policy enforcement in WebView tag in Google Chrome prior to 143.0.7499.192 allowed an attacker who convinced a user to install a malicious extension to inject scripts or HTML into a privileged page via a crafted Chrome Extension.

Microsoft Edge updates itself automatically in the background and applies updates in between restarts. You can also force the browser to get to the latest version by heading to edge://settings/help.

Next week, Microsoft plans to release Microsoft Edge version 144 to all users in the Stable and Extended Stable Channels. As of right now, Edge 144 is available in the Beta Channel, where it also received a small update. It fixed bugs and introduced "contextual nudges" for page summarization with Microsoft 365 Copilot:

Contextual nudges on address bar offering help summarizing webpages. Microsoft Edge for Business now includes an easy way for users to get summaries of their open page from the address bar using Microsoft 365 Copilot Chat. This feature seeks to help users more easily understand relevant content and save time.

You can download Microsoft Edge Beta from the official Edge Insider website.
