Background: Edge was initially built with Microsoft’s own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. In late 2018, it was announced that Edge would be completely rebuilt as a Chromium-based browser with Blink and V8 engines.

Chrome used only WebCore, and included its own JavaScript engine named V8 and a multiprocess system. Chrome for iOS continues to use WebKit because Apple requires that web browsers on that platform must do so.

Remark: Edge was originally based on Chakra but has more recently been rebuilt using Chromium and the V8 engine. V8 is written in C++, and it’s continuously improved.

Vulnerability details: Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability.
