Summary
Helm May Panic Due To Incorrect YAML Content
Details

A Helm contributor discovered an improper validation of type error when parsing Chart.yaml and index.yaml files that can lead to a panic.

Impact

There are two areas of YAML validation that were impacted. First, when a Chart.yaml file had a null maintainer or the child or parent of a dependencies import-values could be parsed as something other than a string, helm lint would panic. Second, when an index.yaml had an empty entry in the list of chart versions Helm would panic on interactions with that repository.

Patches

This issue has been resolved in Helm v3.18.5.

Workarounds

Ensure YAML files are formatted as Helm expects prior to processing them with Helm.
