Summary
Improper Sanitizing of plugin names in helm
Details

Impact

Security researchers at Trail of Bits discovered that plugin names are not sanitized properly. As a result, a malicious plugin author could use characters in a plugin name that would result in unexpected behavior, such as duplicating the name of another plugin or spoofing the output to helm --help.

Specific Go Packages Affected

helm.sh/helm/v3/pkg/plugin

Patches

This issue has been patched in Helm 3.3.2.

Workarounds

Do not install untrusted Helm plugins. Examine the name field in the plugin.yaml file for a plugin, looking for characters outside of the [a-zA-Z0-9._-] range.
