Descriptions

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 expose sensitive data from the controller’s pod filesystem and possibly privilege escalation in multi-tenancy deployments. 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.

Las mitigaciones incluyen herramientas automatizadas en la cadena de trabajo CI/CD del usuario para comprobar que los archivos "kustomization.yaml" sean ajustados a políticas específicas. Esta vulnerabilidad ha sido corregida en kustomize-controller versiones v0.24.0 y ha sido incluida en flux2 versión v0.29.0
