What is CVE-2026-43866?

A deserialization vulnerability exists in the Apache Camel JMS component where the JmsBinding.extractBodyFromJms() method can integrate untrusted data if the mapJmsMessage option is enabled, allowing attackers to publish arbitrary messages. This flaw permits precise manipulation of routing, headers, exchange properties, and error handling without requiring complex deserialization chains. Upgrading to version 4.21.0 or later is highly recommended, with careful management of ObjectMessage consumption to ensure security.

Affected Version(s)

Apache Camel 3.0.0 < 4.14.8

Apache Camel 4.15.0 < 4.18.3

Apache Camel 4.19.0 < 4.21.0
