CVE-2020-15186 Information

Description

In Helm before versions 2.16.11 and 3.3.2 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. This issue has been patched in Helm 3.3.2. A possible workaround is to 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.
