How to fix?

There is no fixed version for Debian:12 gunicorn.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gunicorn package and not the gunicorn package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

Gunicorn version 21.2.0 does not properly validate the value of the 'Transfer-Encoding' header as specified in the RFC standards, which leads to the default fallback method of 'Content-Length,' making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data exposure, session manipulation, SSRF, XSS, DoS, data integrity compromise, security bypass, information leakage, and business logic abuse.
