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. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.
