How to Fix It

The Problem

<script>
  var userInput = getUrlParameter('data');
  document.getElementById('content').innerHTML = userInput;
</script>

The Solution

Use safer alternatives like `textContent` instead of `innerHTML`, avoid `eval()`, and always sanitize user input.

<script>
  var userInput = getUrlParameter('data');
  document.getElementById('content').textContent = userInput; // Safe
</script>

Why This Works

Using safer DOM manipulation methods and avoiding dangerous functions prevents attackers from injecting malicious scripts through user input or URL parameters.
