If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system.

Detailed Information on the risk:
In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements.
