Affected: Bitnami: flux

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.

 https://cve.radiocsirt.org/vuln/ghsa-7pwf-jg34-hxwp GHSA-7pwf-jg34-hxwp — Improper path handling in Kustomization files allows for denial of service 2026-10-06T09:36:33.773163+00:00

Affected: Go: github.com/fluxcd/kustomize-controller, Go: github.com/fluxcd/flux2

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.
