Security-only patch fixing a path traversal vulnerability in chart extraction. Upgrade immediately if you pull charts from untrusted sources.

• securityPatch a chart extraction path traversal — upgrade now

  A crafted Chart.yaml using dot-segments (e.g., '..') in the chart name could cause Helm to write files outside the intended extraction directory. This is a classic directory traversal attack vector. If your pipelines pull charts from public repos, third-party registries, or any source you don't fully control, treat this as critical and upgrade to v3.20.2 today. Teams operating fully air-gapped with only internally authored charts have lower immediate risk, but should still upgrade on the next maintenance window.
