Description (CNA)
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.

A flaw was found in Helm, a package manager for Kubernetes. An attacker could exploit this vulnerability by providing a specially crafted Helm plugin. When such a plugin is installed or updated, Helm incorrectly processes its configuration, allowing the plugin's contents to be written to an arbitrary location on the filesystem. This could lead to unauthorized modification of system files or other critical data.
