Doc Text:
A flaw was found in helm.sh/helm/v3. Improper validation of type errors during parsing of Chart.yaml and index.yaml files can trigger a panic. A remote attacker, requiring user interaction, can trigger this panic via a malformed chart file. This can lead to an application level denial of service.

Description OSIDB Bzimport 2025-08-14 00:01:15 UTC
Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, when parsing Chart.yaml and index.yaml files, an improper validation of type error can lead to a panic. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring YAML files are formatted as Helm expects prior to processing them with Helm.
