CVE-2023-25165
A Helm contributor discovered an information disclosure vulnerability using the
getHostByNametemplate function.Impact
getHostByNameis a Helm template function introduced in Helm v3. The function is able to accept a hostname and return an IP address for that hostname. To get the IP address the function performs a DNS lookup. The DNS lookup happens when used withhelm install|upgrade|templateor when the Helm SDK is used to render a chart.Information passed into the chart can be disclosed to the DNS servers used to lookup the IP address. For example, a malicious chart could inject
getHostByNameinto a chart in order to disclose values to a malicious DNS server.Patches
The issue has been fixed in Helm 3.11.1.
Workarounds
Prior to using a chart with Helm verify the
getHostByNamefunction is not being used in a template to disclose any information you do not want passed to DNS servers.For more information
Helm's security policy is spelled out in detail in our SECURITY document.
