The vulnerability was discovered in the /admin/email/send-test-email endpoint using the POST method. The vulnerable parameter is content, which permits the injection of arbitrary HTML code during the email sending process. While JavaScript code injection is blocked through filtering, HTML code injection remains possible. This vulnerability is fixed in 1.7.6.
