CVE-2026-35206 (GCVE-0-2026-35206)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:02 – Updated: 2026-04-14 14:45

Title

Helm Chart extraction output directory collapse via `Chart.yaml` name dot-segment

Summary

Helm is a package manager for Charts for Kubernetes. In Helm versions <=3.20.1 and <=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. This vulnerability is fixed in 3.20.2 and 4.1.4.

Severity

4.8 (Medium)
