HIGH

Helm 4.0.0-4.1.3 Plugin Metadata - Arbitrary File Write

Title source: manual
STIX 2.1

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.
