What is CVE-2026-103413?
CVE-2026-103413 is a high-severity code injection vulnerability in Apache Camel Karavan, published on 9 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Improper input validation vulnerability in Apache Camel Karavan.
When a deployment was started, Karavan unmarshalled a project's `kubernetes.yaml` and applied every resource it contained to the cluster without restricting the resource kinds, without rejecting security-sensitive pod options, and without pinning the target namespace. An authenticated user of any role could therefore have Karavan apply arbitrary Kubernetes resources within the reach of its service account, including pods requesting hostNetwork, hostPID, hostIPC, hostPath volumes, host ports, privileged containers, privilege escalation or added capabilities.
This issue affects Apache Camel Karavan: from 4.0.0 before 4.22.1.
Users are recommended to upgrade to version 4.22.1, which fixes the issue.
Weakness: CWE-20
