CVE-2020-15185: Helm

Low severity, CVSS 2.7. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Helm Helm: from 2.0.0, before 2.16.11 (fixed in 2.16.11); from 3.0.0, before 3.3.2 (fixed in 3.3.2)
