A Helm contributor discovered an improper validation of type error when parsing Chart.yaml and index.yaml files that can lead to a panic.
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.
This issue has been resolved in Helm v3.18.5.
Ensure YAML files are formatted as Helm expects prior to processing them with Helm.
Helm's security policy is spelled out in detail in our SECURITY document.
