CVE-2026-27172— Apache Camel: Unsafe Java deserialization in camel-consul ConsulRegistry allows arbitrary code execution via malicious values read from the Consul KV store

Quick assessment

Affected
Apache Software Foundation Apache Camel
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是美国阿帕奇（Apache）基金会的一套开源的基于Enterprise Integration Pattern(企业整合模式，简称EIP)的集成框架。该框架提供企业集成模式的Java对象（POJO）的实现，且通过应用程序接口来配置路由和中介的规则。 Apache Camel 3.0.0至4.14.6之前版本和4.15.0至4.18.1之前版本存在代码问题漏洞，该漏洞源于ConsulRegistry组件中反序列化未配置ObjectInputFilter，可能导致任意代码执行。

Vulnerability Title
Apache Camel: Unsafe Java deserialization in camel-consul ConsulRegistry allows arbitrary code execution via malicious values read from the Consul KV store
Source: CVE Program / CVE List V5
Vulnerability Description
The ConsulRegistry in the camel-consul component (class org.apache.camel.component.consul.ConsulRegistry and its inner ConsulRegistryUtils.deserialize method) read Java-serialized values from the Consul KV store and passed them to ObjectInputStream.readObject() without configuring an ObjectInputFilter. An attacker who can write to the Consul KV store backing a Camel ConsulRegistry instance could inject a malicious serialized Java object that is deserialized the next time Camel performs a lookup against that registry, leading to arbitrary code execution in the Camel process. The issue mirrors the class of vulnerability already addressed for other Camel components in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747, and was overlooked during the original remediation of those CVEs. This issue affects Apache Camel: from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.1. Users are recommended to upgrade to version 4.19.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.6. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.1.
