TIMELINE
Sep 18 Reserved by redhat
Sep 18 Published (CNA: redhat)
Oct 9 PATCH SHIPPED — CVE-2026-93567 (Red Hat Build of Apache Camel 3.33.3.SP2). Fixed in Red Hat Build of Apache Camel 3.33.3.SP2 4.1.138.Final-redhat-00001.
Description
A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leading to a malformed HTTP/2 CONNECT request. This can bypass security controls such as tunnel allow-lists or egress policies, resulting in integrity loss.
