CVE-2026-93562: Red Hat AMQ/Camel products may allow HTTP request smuggling
CVE-2026-93562 · published 1 month ago
Summary
The HTTP handling component in several Red Hat products (AMQ Broker, AMQ Clients, Camel for Quarkus, Camel for Spring Boot, and Apicurio Registry) does not fully check malformed Transfer-Encoding headers. An attacker could craft special web requests to slip extra requests past security controls, potentially accessing data they shouldn't. Apply the latest vendor patches or updates that fix the HTTP decoder to protect against this risk.

Original advisory text
Io.netty/netty-codec-http: netty: incomplete validation of malformed transfer-encoding allows http request smuggling
A flaw was found in Netty's HTTP/1 decoder. Incomplete validation of malformed Transfer-Encoding headers allows a remote attacker to perform HTTP request smuggling. By sending specially crafted HTTP requests, an attacker can inject arbitrary HTTP requests, potentially bypassing security controls or accessing unauthorized resources.
