GitHub Vulnerability Alerts

CVE-2025-55199

A Helm contributor discovered that it was possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination.

Impact

A malicious chart can point $ref in values.schema.json to a device (e.g. /dev/*) or other problem file which could cause Helm to use all available memory and have an out of memory (OOM) termination.

Patches

This issue has been resolved in Helm v3.18.5.

Workarounds

Make sure that all Helm charts that are being loaded into Helm doesn't have any reference of $ref pointing to /dev/zero.

CVE-2025-55198

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.
