CloudPirates Helm Charts Workflow Exposes Sensitive Credentials

CVE advisorySeverity: CRITICAL (CVSS 10.0)

CVE-2026-45132

The vulnerability exists within a build-time GitHub Actions workflow used for generating schemas. This is a developer-centric, internal CI/CD process rather than a public-facing service, application, or network-reachable endpoint.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability was discovered in a GitHub Actions workflow used by CloudPirates Open Source Helm Charts, potentially exposing sensitive credentials. While patched, the nature of the exposure within a development pipeline warrants attention to confirm relevance and identify any potential downstream impact.

Attack Path

How an attacker could exploit the issue

An attacker could gain access to sensitive credentials, such as a Personal Access Token and SSH signing key, by leveraging a vulnerable GitHub Actions workflow in the CloudPirates Open Source Helm Charts. This workflow, which is used for generating schemas, improperly handles credentials and code from forks. By exploiting this, an attacker could potentially compromise systems or further escalate their access.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, sensitive credentials, including a Personal Access Token and an SSH signing key, could be exposed to code within a forked repository. This occurs due to unsafe checkout and credential handling in a GitHub Actions workflow.

Operational Fix

Recommended remediation, mitigation, and detection steps

The CloudPirates Open Source Helm Charts project's CI/CD pipeline is impacted by this vulnerability. The immediate first step for teams is to identify if their instance of the Helm charts is using the affected GitHub Actions workflow and, if so, to assess the business criticality and reachability of the compromised credentials. Once ownership is confirmed, a risk-based remediation plan should be developed, which may involve coordinating with the vendor for updated configurations.

Frequently asked questions

What is CloudPirates Open Source Helm Charts?

It is a collection of Helm charts used to package and deploy applications on Kubernetes. Developers and teams use these templates to simplify the configuration and installation of software within their clusters.

What does CWE-94 mean for CVE-2026-45132?

This CVE falls under the weakness class of Improper Control of Generation of Code (CWE-94). In this context, it means the automated workflow was written in a way that inadvertently allowed external, untrusted code to run within the environment, leading to the unauthorized disclosure of sensitive security credentials.

How does an attacker trigger this vulnerability?

The issue is triggered when the automated workflow processes code from a fork. Because the workflow configuration does not properly isolate the build environment, it creates an opportunity for that external code to interact with credentials. If you do not use forks with this specific workflow, or if the workflow is not triggered, this path is not engaged.

Is my environment at risk from this CVE?

According to Halo Surface Signal, this vulnerability is very unlikely to affect public-facing services because it exists within an internal CI/CD process. Since it involves a developer-centric build task for generating schemas rather than a reachable network application, the risk is primarily contained to your internal development pipeline.

What should I do if I use these Helm charts?

First, verify if your development pipeline uses the specific GitHub Actions workflow affected by this issue. If you are using that workflow, determine if any Personal Access Tokens or SSH keys were active or accessible during the period the vulnerable code was in use. Revoke and rotate any potentially compromised credentials to ensure the security of your repositories.
