CVE-2025-55199

6.5 mediumEPSS 0.3%

Medium (6.5) in helm helm. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in helm.sh/helm/v3 3.18.5.

Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is 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. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero.
