Description: paicoding commit 766c48b through commit 903adce contains a stored cross-site scripting vulnerability in payment notifications, where NotifyMsgListener inserts the payer's display name unescaped and notify-system-item.html renders it via th:utext. Authenticated attackers can set a malicious display name and start a pending payment on a paid article, executing script in the author's browser when the author views notifications.
