CVE-2026-40858 · Severity: high · CVSS 8.8 · Published 2026-04-27

Apache Camel is a popular integration framework used to connect different software applications. A security vulnerability in its Infinispan component allows an attacker who can write data to a shared cache to execute malicious code on the server. This could lead to a full system takeover, data theft, or disruption of business operations.

Technologies: [org.apache.camel:camel-infinispan (Maven)](https://junglewise.ai/threats/technologies/org-apache-camel-camel-infinispan), [Red Hat build of Apache Camel for Quarkus](https://junglewise.ai/threats/technologies/build-of-apache-camel-for-quarkus), [Red Hat build of Apache Camel for Spring Boot](https://junglewise.ai/threats/technologies/red-hat-build-of-apache-camel-for-spring-boot). Vendors: [Maven](https://junglewise.ai/threats/vendors/maven), [Red Hat](https://junglewise.ai/threats/vendors/red-hat).

## How to fix

- org.apache.camel:camel-infinispan (Maven): upgrade to 4.14.7 or later

  ```sh
  # set org.apache.camel:camel-infinispan to 4.14.7 in your pom.xml or build.gradle
  ```


## Technical details

The camel-infinispan component's ProtoStream-based remote aggregation repository utilizes java.io.ObjectInputStream to deserialize data from a remote Infinispan cache without implementing an ObjectInputFilter. An attacker with the ability to write to the Infinispan cache can inject a malicious serialized Java object. When the Camel application performs standard repository operations such as 'get' or 'recover', it deserializes this object, leading to arbitrary code execution (RCE) in the application's context. The vulnerability is mitigated in versions 4.14.7, 4.18.2, and 4.20.0 by introducing proper filtering during deserialization.

## Affected products

- Apache Software Foundation Apache Camel 4.0.0 to 4.14.6, 4.15.0 to 4.18.1, 4.19.0 to 4.19.9
- Red Hat Red Hat Build of Apache Camel for Quarkus 3.33
- Red Hat Red Hat build of Apache Camel for Spring Boot 4.18.1
