Vulnerability from github – Published: 2026-05-04 20:12 – Updated: 2026-05-13 13:39

Summary

Argo vulnerable to exposure of artifact repository credentials

Details

Summary

The workflow executor logs all artifact repository credentials (S3 access keys, secret keys, GCS service account keys, Azure account keys, Git passwords, etc.) in plaintext on artifact operation. Any user with read access to workflow pod logs can extract these credentials.

Note: This is an incomplete fix of CVE-2025-62157

Details

The logging driver passes the entire ArtifactDriver struct to the structured logger, for example: https://github.com/argoproj/argo-workflows/blob/59f1089b9875723ddffd524513e6bd5cb37e5e31/workflow/artifacts/logging/driver.go#L24

Exposed credential fields: - S3 (workflow/artifacts/s3/s3.go): AccessKey, SecretKey, SessionToken, ServerSideCustomerKey - OSS (workflow/artifacts/oss/oss.go): AccessKey, SecretKey, SecurityToken - GCS (workflow/artifacts/gcs/gcs.go): ServiceAccountKey

PoC

Create template

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: cred-leak-test
  namespace: argo
spec:
  entrypoint: main
  templates:
  - name: main
    container:
      image: alpine:3.13
      command: [sh, -c]
      args: ["echo 'hello' > /tmp/output.txt"]
    outputs:
      artifacts:
      - name: output
        path: /tmp/output.txt
        s3:
          endpoint: minio:9000
          insecure: true
          bucket: my-bucket
          key: test-output.txt
          accessKeySecret:
            name: my-minio-cred
            key: accesskey
          secretKeySecret:
            name: my-minio-cred
            key: secretkey

Then check the logs kubectl -n argo logs "cred-leak-test" -c wait

Impact

Any user with Kubernetes RBAC permissions to read pod logs in the workflow namespace can extract artifact repository credentials.

Severity ?

8.5 (High)

CVE-2026-42295 (GCVE-0-2026-42295)

Vulnerability from cvelistv5 – Published: 2026-05-09 03:48 – Updated: 2026-05-11 14:47

Title

Argo Workflows: Exposure of artifact repository credentials

Summary

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. From version 4.0.0 to before version 4.0.5, the workflow executor logs all artifact repository credentials (S3 access keys, secret keys, GCS service account keys, Azure account keys, Git passwords, etc.) in plaintext on artifact operation. Any user with read access to workflow pod logs can extract these credentials. This issue has been patched in version 4.0.5.

Severity ?
