CVE-2022-24878: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

May 20, 2022

Flux is an open and extensible continuous delivery solution for Kubernetes. Path Traversal in the kustomize-controller via a malicious kustomization.yaml allows an attacker to cause a Denial of Service at the controller level. Workarounds include automated tooling in the user’s CI/CD pipeline to validate kustomization.yaml files conform with specific policies. This vulnerability is fixed in kustomize-controller v0.24.0 and included in flux2 v0.29.0. Users are recommended to upgrade.
