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.
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.
