CVE-2025-55198: Helm

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Helm Helm: before 3.18.5 (fixed in 3.18.5)
