What is CVE-2026-40858?

The vulnerability in Apache Camel's Infinispan component arises from an insecure deserialization process involving ProtoStream. Specifically, the component employs java.io.ObjectInputStream to deserialize data from a remote Infinispan cache without utilizing an ObjectInputFilter, exposing the application to potential remote code execution. If an attacker can write to the Infinispan cache, they can craft a malicious serialized Java object. This object, when retrieved during aggregation operations such as 'get' or 'recover', can execute arbitrary code within the application context. Affected versions include Apache Camel from 4.0.0 prior to 4.14.7, from 4.15.0 prior to 4.18.2, and from 4.19.0 prior to 4.20.0. Users are advised to update to versions 4.20.0 or 4.14.7/4.18.2 as applicable to mitigate the risks.

Affected Version(s)

Apache Camel 4.0.0 < 4.14.7

Apache Camel 4.15.0 < 4.18.2

Apache Camel 4.19.0 < 4.20.0
