CVE-2026-85245

/// Technical description

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 re
