Summary

A vulnerability in the Apache Camel Thrift component causes incoming data to be unmarshalled into the shared defaultInstance of the target type rather than a fresh copy. As a result, state from one message remains visible to subsequent messages of the same type, potentially leading to data disclosure between different senders.

Risk Assessment

In deployments serving multiple tenants or users through the same route, data from one party may be disclosed to another. Concurrent exchanges may also observe each other's partially written state.

Recommendation

Upgrade Apache Camel to version 4.23.0 (or 4.18.5 for the 4.18.x LTS stream, 4.22.1 for the 4.22.x LTS stream). If immediate upgrade is not possible, copy the unmarshalled body into a new instance immediately after the data format runs and do not retain references to the returned object.

Original NVD description (English source)

Exposure of Data Element to Wrong Session vulnerability in Apache Camel Thrift component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Thrift data format unmarshalled incoming data into the shared defaultInstance of the target type rather than into a fresh copy, and returned that shared object as the exchange body. Because the instance is shared process-wide, state written while unmarshalling one message stayed on the object and was visible to every later message that used the same type. Fields absent from a later payload retained the previous message's values, so content belonging to one sender could be read while processing another sender's message, and concurrent exchanges could observe each other's partially written state. In a deployment that serves more than one tenant or user through the same route, that is disclosure of one party's data to another. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Unmarshalling now deserializes into a copy, so each exchange gets its own instance and no state carries between messages. For deployments that cannot upgrade immediately, copy the unmarshalled body into a new instance immediately after the data format runs, and do not retain references to the returned object.
