What it is

🚨 Unrestricted file uploads are a recipe for disaster! In STAGGS versions up to 2.11.0, anyone can slip a web shell into your server, opening the door to total chaos. 🔥 Think of it like a restaurant allowing anyone to drop off any dish without checking it—if someone delivers a plate of poison, it’s going to ruin the whole kitchen! With this vulnerability, an attacker could upload a malicious web shell and take full control of your server. This means they could access sensitive data, manipulate files, and even launch attacks on other systems—all with just a single uploaded file. The potential fallout? Absolutely devastating!
