Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Camel's camel-coap, camel-google-pubsub, camel-jms and camel-sjms modules are affected from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.2, and from 4.19.0 before 4.20.0. An attacker with producer access to a JMS or equivalent broker consumed by a Camel route can inject case-variant internal headers, which can lead to remote code execution or arbitrary file write in routes that forward messages to header-driven components. Upgrade to 4.14.6, 4.18.2, or 4.20.0 depending on your release stream.
