Sensitive-file disclosure via kustomization path traversal
Published May 6, 2022 · Updated Apr 23, 2025
Path traversal in Flux kustomize-controller before 0.24.0 allows remote authenticated users to read sensitive files via a malicious kustomization.yaml. The controller joins attacker-controlled resource paths without constraining them to the intended kustomization directory, permitting traversal into its pod filesystem. Exploitation requires the ability to submit or cause reconciliation of a crafted Kustomization; exposed files can disclose credentials and enable privilege escalation in multi-tenancy deployments.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=flux2 < v0.29.0
- Affected versionversion=kustomize-controller < v0.24.0
