| Doc Text: |
A flaw was found in actix-http. This vulnerability allows unauthenticated remote attackers to perform HTTP request smuggling. By sending specially crafted HTTP/1.1 requests that include both Content-Length and Transfer-Encoding: chunked headers, an attacker can desynchronize backend requests through a front-end intermediary. This desynchronization enables the attacker to smuggle malicious HTTP requests to the Actix service, potentially leading to unauthorized actions or data manipulation.
