Stored XSS in Projectworlds Expense Management System 1.0 allows remote authenticated users to execute scripts via crafted user names. The user-creation handler stores the Name field without sanitization, and print views render it without HTML output encoding. Administrative access is required to create the record, and another user must open its print view, allowing script execution in that user's browser.
