🔥 An authenticated admin with a single wrong upload could unleash chaos! Magento versions 2.4.0 and 2.3.5p1 have a critical file upload vulnerability just waiting to be exploited! Think of it like a restaurant where a chef can add a secret ingredient to every dish without anyone double-checking the recipe — if that ingredient is toxic, the whole meal becomes a disaster. In this case, a crafty admin could upload malicious files, leading to a full-blown kitchen nightmare! If exploited, an attacker could execute arbitrary code on the server, allowing them to take complete control over the Magento instance. This means they could access sensitive data, modify the system settings, or even bring down the whole site. Absolutely devastating!
