NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-actix-http package and not the rust-actix-http package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

actix-http versions before 3.12.1 contain an HTTP request smuggling vulnerability in the HTTP/1.1 parser that accepts requests with both Content-Length and Transfer-Encoding: chunked headers. Unauthenticated remote attackers can exploit this through a front-end intermediary to desynchronize backend requests and smuggle malicious HTTP requests to the Actix service.
