Medium (6.5) in helm helm. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in helm.sh/helm/v3 3.17.3.
Helm is a package manager for Charts for Kubernetes. A JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow. This issue has been resolved in Helm v3.17.3.
