Internet Shortcut Files Security Feature Bypass Vulnerability. An attacker must send the user a malicious file and convince them to open it. An unauthenticated attacker could send the targeted user a specially crafted file that is designed to bypass displayed security checks. However, the attacker would have no way to force a user to view the attacker-controlled content. Instead, the attacker would have to convince them to take action by clicking on the file link.
