NVD Description

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

A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources.
