CVE-2026-42295: Argoproj Argo Workflows

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Argoproj Argo Workflows: from 4.0.0, before 4.0.5 (fixed in 4.0.5)
