A vulnerability was found in Helm up to 2.16.10/3.3.1. It has been rated as critical. This issue affects some unknown functionality of the file Chart.yaml. The manipulation of the argument alias with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented 09/17/2020 (GitHub Repository). The advisory is shared at github.com. The identification of this vulnerability is CVE-2020-15184 since 06/25/2020. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

Upgrading to version 2.16.11 or 3.3.2 eliminates this vulnerability.
