Short explanation
A data disclosure vulnerability (CVE-2026-85245) has been identified in the Apache Camel Thrift component, caused by a shared deserialization target leaking session data across exchanges.
This vulnerability can lead to sensitive user data being inadvertently exposed to other users in multi-tenant environments sharing the same route.
What should be done?
- Upgrade to Apache Camel 4.23.0
- Users on the 4.18.x LTS stream should upgrade to 4.18.5
- Users on the 4.22.x LTS stream should upgrade to 4.22.1
Chain of evidence and sources
Thrift veri biçimi, gelen verileri taze bir kopya yerine paylaşılan defaultInstance nesnesine seri durumdan çıkarmaktadır.
Etkilenen sürümler arasında 4.0.0 ile 4.18.5 öncesi ve 4.19.0 ile 4.22.1 öncesi yer almaktadır.
Sorunu gidermek için Apache Camel 4.23.0, 4.18.5 veya 4.22.1 sürümlerine yükseltme yapılması önerilir.
Show the technical text from the sources
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.
