Descriptions

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.

En Helm versiones anteriores a 2.16.11 y 3.3.2, los nombres de los plugins no son saneados apropiadamente. Como resultado, un autor de plugin malicioso podría usar caracteres en un nombre de plugin que resultaría en un comportamiento inesperado, como duplicar el nombre de otro plugin o falsificar la salida en "helm --help". Este problema ha sido corregido en Helm versión 3.3.2. Una posible solución es no instalar plugins de Helm que no son de confianza. Examine el campo "name" en el archivo "plugin.yaml" en busca de un plugin, buscando caracteres fuera del rango [a-zA-Z0-9 ._-]
