CVE-2026-28368 Details
Description
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.
A request smuggling vulnerability has been identified in Undertow. This issue arises from a flaw in how Undertow parses header names in comparison to upstream proxies. The discrepancy allows remote attackers to craft requests that exploit this inconsistency, potentially bypassing security controls and accessing unauthorized resources.
