CVE-2022-24877

CRITICAL

fluxcd flux2 and kustomize-controller < 0.29.0 and < 0.24.0 - Path Traversal via Malicious kustomization.yaml

Title source: llm
STIX 2.1

Description

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.
