Vulnerability Title
Helm has a path traversal in plugin metadata version enables arbitrary file write outside Helm plugin directory
Source: CVE Program / CVE List V5
Vulnerability Description
Helm is a package manager for Charts for Kubernetes. From 4.0.0 to 4.1.3, a specially crafted Helm plugin, when installed or updated, will cause Helm to write the contents of the plugin to an arbitrary filesystem location. To prevent this, validate that the plugin.yaml of the Helm plugin does not include a version: field containing POSIX dot-dot path separators ie. "/../". This vulnerability is fixed in 4.1.4.
