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

Description A remote code execution issue exists due to the way the scripting engine handles objects in memory. This could allow an attacker to corrupt memory and execute arbitrary code in the context of the current user, potentially gaining the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. The vulnerability can be exploited through a web-based attack scenario, where an attacker hosts a specially crafted website designed to exploit the vulnerability through Microsoft Edge (HTML-based).

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
