Severity CVSS v4.0:

Pending analysis

CWE-74 Injection

Description

In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with the last one always used. If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin&#39;s install hooks, causing a local execution attack.<br /> To perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 2.16.11 and Helm 3.3.2.<br /> As a possible workaround make sure to install plugins using a secure connection protocol like SSL.
