{"id":"BIT-helm-2026-35206","summary":"Helm Chart extraction output directory collapse via `Chart.yaml` name dot-segment","details":"Helm is a package manager for Charts for Kubernetes. In Helm versions \u003c=3.20.1 and \u003c=4.1.3, a specially crafted Chart will cause helm pull --untar  [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the --destination and --untardir flags), rather than the expected output directory suffixed by the chart's name.
