Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in the user profile text fields of Altium 365. It occurs because the server does not properly sanitize input, allowing authenticated users to inject malicious HTML and JavaScript code using whitespace-based attribute parsing bypass techniques. The injected code is saved and executed when other users view the affected profile page.
