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.

GHSA-7pwf-jg34-hxwpImproper path handling in Kustomization files allows for denial of service2022-05-20ghsa · osvUS
The kustomize-controller enables the use of Kustomize’s functionality when applying Kubernetes declarative state onto a cluster. A malicious user can use a specially crafted `kustomization.yaml` to cause Denial of Service at controller level. In multi-tenancy deployments this can lead to multiple tenants not being able to apply their Kustomizations until the malicious `kustomization.yaml` is removed and the controller restarted. ### Impact Within the affected versions, users with write access to a Flux source are able to craft a malicious `kustomization.yaml` file which causes the controller to enter an endless loop. ### Patches This vulnerability was fixed in kustomize-controller v0.24.0 and included in flux2 v0.29.0 released on 2022-04-20. The changes introduce better handling of Kustomization files blocking references that could lead to endless loops. ### Credits The Flux engineering team found and patched this vulnerability. ### For more information If you have any questions or comments about this advisory please open an issue in the [flux2 repository](http://github.com/fluxcd/flux2).
