CVE-2020-15184

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.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
