A flaw was found in Undertow.

Published Mar 27, 2026 · corrected/updated Oct 14, 2026 · redhat build of apache camel - hawtio · evidence confidence high

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.
