What it is

🚨 An unauthenticated POST request is all it takes for an attacker to upload arbitrary files to your SonLogger instance. This vulnerability is a ticking time bomb waiting to go off! ⚡ Think of it like a restaurant kitchen where the chef doesn't check the delivery orders—anyone can drop off whatever they want without any questions asked. Just like that kitchen, SonLogger allows potentially malicious files to be uploaded without a second glance! This could lead to devastating consequences! An attacker could upload malicious files that might compromise your server, execute code, or even cause data breaches. Imagine giving unauthorized access to your sensitive information just because the file upload door was wide open!
