CVE-2020-15185 Information

Description

In Helm before versions 2.16.11 and 3.3.2 a Helm repository can contain duplicates of the same chart with the last one always used. If a repository is compromised this lowers the level of access that an attacker needs to inject a bad chart into a repository. To perform this attack an attacker must have write access to the index file (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the index file in the Helm repository cache before installing software.
