Name of the Vulnerable Software and Affected Versions Microsoft Edge (affected versions not specified)

This could allow an attacker to execute arbitrary code with the same user rights as the current user by using a specially crafted web page. If the current user has administrative rights, the attacker could take control of the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.
