CVE-2020-15184: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

May 24, 2021 (updated November 19, 2021)

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.
