Netty is an asynchronous, event-driven network application framework. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.xml. XmlFrameDecoder.decode() failed to preserve closing-tag parser state across invocations, so an unauthenticated remote attacker could trickle-feed repeated Affected products named by the advisory: Red Hat build of Apache Camel 4.18.4 for Spring Boot 3.5.16; Red Hat Single Sign-On 7.

- Mitigation guidance
- Red Hat products do not use the vulnerable XmlFrameDecoder component. No mitigation is required for standard product deployments. Custom applications built on Red Hat middleware that explicitly instantiate XmlFrameDecoder should avoid processing untrusted XML input or upgrade to netty-codec-xml 4.1.136.Final or later.
