Partner Software's Partner Software application and Partner Web application allows an authenticated user to add notes on the 'Notes' page when viewing a job but does not completely sanitize input, making it possible to add notes with HTML tags and JavaScript, enabling an attacker to add a note containing malicious JavaScript, leading to stored XSS (cross-site scripting).
