What it is

🚨 A web shell can be uploaded with no checks at all — like leaving the back door to your house wide open without a lock! 🔥 Imagine running a restaurant where the kitchen staff accepts any dish anyone brings in, regardless of what's in it. That's essentially what's happening here with the King Addons plugin: it allows users to upload any file type, even dangerous ones like web shells, without verifying what's being offered. An attacker could exploit this vulnerability to upload a web shell to your server, effectively gaining complete control over your site. This is absolutely devastating — they could manipulate data, steal sensitive information, or even bring your entire site down. Think of it as an intruder freely roaming around your virtual restaurant, causing chaos at will.
