Description
In SilverStripe through 4.5, files uploaded via Forms to folders migrated from Silverstripe CMS 3.x may be put to the default "/Uploads" folder instead.

This module is installed and enabled by default on the Common Web Platform (CWP). The vulnerability only affects files uploaded after an upgrade to 4.x.
