What it is

🚨 An unauthenticated attacker can effortlessly inject data into legitimate requests, effectively masquerading as victims—just like a thief slipping a false order into a restaurant's kitchen! Imagine a restaurant where a sneaky individual convinces the chef to prepare meals they never ordered by presenting fake tickets—this is what request smuggling does to your web applications, allowing intruders to pose as your users and manipulate the system without detection. This vulnerability is absolutely devastating! An attacker could not only impersonate legitimate users but also compromise the entire system's confidentiality, integrity, and availability. If exploited, it could lead to unauthorized access to sensitive data or even total system failure, putting your business at significant risk.
