XSS Scripting is a severe vulnerability that at a time Microsoft was also having this vulnerability. Hello everyone, today I am going to tell you what XSS Scripting is. We are going to learn what is XSS scripting in depth. So, let's start.

What is XSS Scripting?

XSS Scripting means Cross-Site Scripting.

Did you ever try inspecting any website? You can do that by pressing Ctrl + Shift + I.

If you inspect any website you will get a panel where you can change the HTML of the website for you(Client Side).

Assume what happens if you can change the HTML code of that website for all.

If that happens, then you will be able to hack the website using JavaScript

How?

• Did you ever comment on Facebook? If you comment on Facebook, your comment will be sent to the server and then sent back to the users. So, if you comment on some malicious JavaScript code, there will be some changes to the server. So, it affects facebook's server.

So, many websites like Facebook, YouTube, Google doesn't have this kind of vulnerabilities.

But there is a chance that some websites can have this vulnerability.
