Background
django-helpdesk is a Python package available on PyPI that provides a ticketing system for customer support. It is commonly used in web applications to manage and track user inquiries. The package allows users to create, update, and close tickets, as well as communicate with customers. However, an issue has been identified in the package that makes it vulnerable to cross-site scripting (XSS) attacks.
