CVE-2026-42295 Details
Description
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.
A vulnerability exists in Argo Workflows versions 4.0.0 prior to 4.0.5, where the workflow executor logs artifact repository credentials in plaintext. This includes S3 access keys, secret keys, GCS service account keys, Azure account keys, and Git passwords. Any user with read access to workflow pod logs can extract these credentials. The issue arises because the logging driver passes the entire ArtifactDriver struct to the structured logger, exposing sensitive information. This vulnerability can be reproduced by creating a workflow that uses artifact repositories requiring credentials, and then checking the logs of the workflow pod.
Users can upgrade to Argo Workflows version 4.0.5, where this vulnerability has been patched.
