CVE-2019-14228 is a medium-severity flaw (CVSS 6.1) affecting xavier. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Xavier PHP Management Panel 3.0 is vulnerable to Reflected POST-based XSS via the username parameter when registering a new user at admin/includes/adminprocess.php. If there is an error when registering the user, the unsanitized username will reflect via the error page.
