NVD Description

Note: Versions mentioned in the description apply only to the upstream pcs package and not the pcs package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Tornado before 6.4.1 ignores duplicate Transfer-Encoding: chunked headers, treating requests as having no message body and parsing the chunked body as a subsequent request. Attackers can exploit this inconsistency when Tornado is deployed behind proxies to perform HTTP request smuggling, enabling access control bypass, cache poisoning, or connection desynchronization.
