CVE-2026-40858

Apache Software Foundation Apache Camel, Red Hat build of Apache Camel 4.18.1 for Spring Boot 3.5.14, Red Hat Build of Apache Camel 4.18 for Quarkus 3.33

The camel-infinispan component's ProtoStream-based remote aggregation repository deserializes data read from a remote Infinispan cache using java.io.ObjectInputStream without applying any ObjectInputFilter. An attacker who can write to the Infinispan cache used by a Camel application can inject a crafted serialized Java object that, when read during normal aggregation repository operations such as get or recover, results in arbitrary code execution in the context of the application. This issue affects Apache Camel: from 4.0.0 before 4.14.7, from 4.15.0 before 4.18.2, from 4.19.0 before 4.20...
