CVE-2025-27636

/// Technical description

Bypass/Injection vulnerability in Apache Camel components under particular conditions.

This issue affects Apache Camel: from 4.10.0 through <= 4.10.1, from 4.8.0 through <= 4.8.4, from 3.10.0 through <= 3.22.3.

Users are recommended to upgrade to version 4.10.2 for 4.10.x LTS, 4.8.5 for 4.8.x LTS and 3.22.4 for 3.x releases.

This vulnerability is present in Camel's default incoming header filter, that allows an attacker to include Camel specific

headers that for some Camel components can alter the behaviours such as the camel-bean component, to call another method

on the bean, than was coded in the application. In the camel-jms component, then a malicious header can be used to send

the message to another queue (on the same broker) than was coded in the application. This could also be seen by using the camel-exec component

The attacker would need to inject custom headers, such as HTTP protocols. So if you have Camel applications that are

directly connected to the internet v
