💉 XSS: Cross-Site Swagging

by ByteBandit

Ah yes... XSS. Cross-Site Scripting. Or as I like to call it, "eXecute Some Scripts" — straight into your browser like it's my personal command line.

If you’ve never turned someone’s comment box into a JavaScript playground, are you even hacking?

Here’s the deal: XSS happens when a site trusts user input too much. You drop a little sneaky payload like:

<script>alert("Hacked by ByteBandit")</script>
    

And boom — you’ve got code executing right in the victim’s browser. Cookies? Snagged. Sessions? Hijacked. Reputation? Wrecked (for them, not me).

Types? Oh yeah, there’s more than one flavor:

• Stored XSS – Leave your payload behind like a landmine.
• Reflected XSS – Instant karma via URL.
• DOM-based XSS – Because sometimes the browser's just too trusting.

The cure? html.escape(), input sanitization, CSPs — aka the boring stuff devs forget when they're too busy copy-pasting from Stack Overflow.

Me? I see an unsanitized field and I see art waiting to happen.

Inject responsibly. Or don’t. I’m not your sysadmin.
