Lifecycle Timeline
1DescriptionNVD
Helm is a tool for managing Charts (packages of pre-configured Kubernetes resources). In versions of helm prior to 3.6.1, a vulnerability exists where the username and password credentials associated with a Helm repository could be passed on to another domain referenced by that Helm repository. This issue has been resolved in 3.6.1. There is a workaround through which one may check for improperly passed credentials. One may use a username and password for a Helm repository and may audit the Helm repository in order to check for another domain being used that could have received the credentials. In the index.yaml file for that repository, one may look for another domain in the urls list for the chart versions. If there is another domain found and that chart version was pulled or installed, the credentials would be passed on.
