CVE-2026-85245— Apache Camel: Camel-Thrift Cross-Exchange Data Disclosure via a Shared Deserialization Target

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Camel Thrift 组件存在“数据元素暴露至错误会话”的漏洞。 受影响版本：Apache Camel 4.0.0 至 4.18.4，以及 4.19.0 至 4.22.0。 问题根源在于，Thrift 数据格式在反序列化（unmarshal）传入数据时，并未创建新的目标类型实例，而是将数据写入共享的默认实例（defaultInstance），并将该共享对象作为消息交换体（exchange body）返回。由于该实例在整个进程中共享，在反序列化某条消息时写入的状态会保留在对象中，并被后续使用相同类型

Vulnerability Title
Apache Camel: Camel-Thrift Cross-Exchange Data Disclosure via a Shared Deserialization Target
Source: CVE Program / CVE List V5
Vulnerability 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 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.
