Vulnerability Description

An issue was discovered in UiPath App Studio 21.4.4. There is a persistent XSS vulnerability in the file-upload functionality for uploading icons when attempting to create new Apps.

This then allows the file to be stored and retrieved from the server by other users in the same organization.
