⚠️ One sneaky parameter is all it takes! In le.cms versions 1.4 and earlier, an attacker can upload malicious files simply by manipulating the submit0 parameter — a recipe for disaster! Think of it like a restaurant that lets diners add any dish to their order without checking if the cook is qualified — they could end up serving some very toxic meals! An attacker could potentially gain unauthorized access to your admin panel, uploading and executing harmful files that compromise the entire system. This could lead to data breaches, site defacement, or even complete control of the server, which is absolutely devastating.
