  1. XSS

When the payload is pasted in comment area, the js code is repeat executed, and if you post it with Burp or any tools, this payload will become a storage xss in this page.

By this xss, you can direct any url you want.

payload:

<details open ontoggle=window.location.replace('https://www.google.com');>

Fix the vulnerability: please use html entity encode
