NVD Description

Note: Versions mentioned in the description apply only to the upstream eap8-activemq-artemis-hqclient-protocol package and not the eap8-activemq-artemis-hqclient-protocol package as distributed by RHEL. See How to fix? for RHEL: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.
