This is not a vulnerability. In Windows, you can put a file in a directory that the user does not have access to, but if the user can produce the name of the file, they can still access it. This works because Windows by default enables “bypass traversal checks”, which means that you can access anything you can name.

Background: Trend Micro Apex One as a Service is a centrally managed anti-malware solution that protects endpoints (servers, desktops, and portable endpoints) from a wide variety of Internet threats.
