Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-56hp-xqp3-w2jf. This link is maintained to preserve external references.
Original 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.

helmhelmDetection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for helm.sh/helm/v3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update helm.sh/helm/v3 to 3.6.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7jr6-prv4-5wf5 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Red Hat Advanced Cluster Management for Kubernetes: In Red Hat Advanced Cluster Management for Kubernetes (RHACM) the affected components are using helm chart provided by the installer, so components are not using untrusted charts except in the application-lifecycle area. For this reason we marked the impact as low.…
