        You need to pop an alert in origin https://avlidienbrunn.se  if I understand it correctly. Any hints?

        You need to craft a link that will trigger an XSS payload in avlidienbrunn.se origin

        the solution is related to header injection? CRLF injjection? I will try later

        The goal of such a challenge is to find it by yourself. Just dig it with Burp and ask yourself how you can craft this link, pure logic 😉👌

        I don't understand why there's no "Referer disallowed" message in BurpSuite's repeater.

        Referer header is to be defined by your browser based on the current location, if you're not using browser, the header isn't defined 😉
