Stored XSS into HTML context with nothing encoded

https://portswigger.net/web-security/cross-site-scripting/stored/lab-html-context-nothing-encoded

Let's comment the following payload below the post:

<script>alert("1");</script>

Since this payload is stored on the page in the form of a comment it will be executed for every user that visits the page.

We have solved the lab.
