{"id":"BIT-helm-2025-55199","summary":"Helm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion","details":"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.
