A remote attacker could exploit an inconsistent interpretation of HTTP requests, known as HTTP Request/Response Smuggling, by sending a specially crafted request with an invalid chunk extension. This vulnerability allows an attacker to manipulate the way HTTP requests are processed, potentially leading to the bypassing of security controls, cache poisoning, or other malicious activities." ],
