CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Helm versions 2.x through 2.15.1
Description
The issue allows a maliciously designed chart to include sensitive content, such as
/etc/passwd, or to execute a denial of service (DoS) via a special file, like /dev/urandom, using symlinks. This is a client-only issue and does not affect any version of Tiller.Recommendations
For Helm versions 2.x through 2.15.1, update to version 2.15.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of symlinks in charts to minimize the risk of exploitation. Avoid using commands that deal with loading a chart as a directory or packaging a chart from untrusted sources until the issue is resolved.
