NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-gunicorn package and not the python3-gunicorn package as distributed by SLES. See How to fix? for SLES:15.4 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.
