  "summary" : "Improper use of metav1.Duration allows for Denial of Service",
  "details" : "Flux controllers within the affected versions range are vulnerable to a denial of service attack. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed.\n\nThe issue has two root causes: a) the Kubernetes type `metav1.Duration` not being fully compatible with the Go type `time.Duration` as explained on [upstream report](https://github.com/kubernetes/apimachinery/issues/131); b) lack of validation within Flux to restrict allowed values.\n\n### Workarounds\n\nAdmission controllers can be employed to restrict the values that can be used for fields `.spec.interval` and `.spec.timeout`, however upgrading to the latest versions is still the recommended mitigation.\n\n### Credits\n\nThis issue was reported by Alexander Block (@codablock) through the Flux security mailing list (as [recommended](https://fluxcd.io/security/#report-a-vulnerability)).\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Open an issue in any of the affected repositories.\n- Contact us at the CNCF Flux channel.\n\n### References\n\n- https://github.com/kubernetes/apimachinery/issues/131\n\n",
