Put simply

Think of this vulnerability like a restaurant that serves meals without checking the ingredients — a rogue chef could sneak in any recipe and take over the kitchen! This deserialization vulnerability allows an attacker to send malicious data that the server trusts and processes without verification, potentially leading to Remote Code Execution (RCE).
