CVE-2020-4053: Helm

Medium severity, CVSS 6.8. EPSS: 1.5% chance of exploitation in the next 30 days.

In Helm greater than or equal to 3.0.0 and less than 3.2.4, a path traversal attack is possible when installing Helm plugins from a tar archive over HTTP. It is possible for a malicious plugin author to inject a relative path into a plugin archive, and copy a file outside of the intended directory. This has been fixed in 3.2.4.

Affected products

• Helm Helm: from 3.0.0, before 3.2.4 (fixed in 3.2.4)
