Assuming reviewer focused on sanitize your input. To keep yourself safe from XSS, you must sanitize your input. Your application code should never output data received as input directly to the browser without checking it for malicious code.
I understand about it, that why I always use {{ }} from Laravel Blade to sanitize the input value https://prnt.sc/u1bbpv, so it will be helpful if you guys can show me how to reproduce the issue
That looks ok. I don’t think the issue is there. I once had similar issue. But, I found where it is. Please check codes that are written like that {!!}
