Cross site scripting Meta tag issue

Hello everyone,

The below line of code is flag as being vulnerable for cross site scripting (xss)

How do I manually test the page with a real code test ?
Already try it in the url addres bar:

and this test is sending the user to my non-found page which is a good thing

Second question:
If I change the line of code in question to the below solution should solve the problem?

[php]<meta property=“og:url” content="<?php $url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; echo htmlspecialchars($url); ?>" />[/php]

Thank you for your help in advance :slight_smile:

I know this thread is a little old, but here’s what I do ->
[php]header(‘x-xss-protection: 1; mode=block’);[/php]

The proper place for that code is in the Server config one time rather than many times in many scripts.

Hello Kevin and Stride64,
