Description Dhananjay Arunesh 2020-09-24 11:12:55 UTC 
In Helm before versions 2.16.11 and 3.3.2 there is a bug in which the alias field on a Chart.yaml is not properly sanitized. This could lead to the injection of unwanted information into a chart. This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the dependencies field of any untrusted chart, verifying that the alias field is either not used, or (if used) does not contain newlines or path characters.
