Argo Workflow may expose artifact repository credentials
Date: 2025-10
Affected: go/github.com/argoproj/argo-workflows/v3, go/github.com/argoproj/argo-workflows/v3
Attack vector: data-exfiltration
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2025-62157
CWE: CWE-522

### Summary An attacker who has permissions to read logs from pods in a namespace with Argo Workflow can read `workflow-controller` logs and get credentials to the artifact repository. ### Details An attacker, by reading the logs of the workflow controller pod, can access the artifact repository, and steal, delete or modify the data that resides there. The `workflow-controller` logs show the credentials in plaintext. <img width="1366" alt="screen" src="https://github.com/user-attachments/assets/5642b2be-edcf-4050-bf47-747d05352698" /> ### Impact An attacker with access to pod logs in the `argo` namespace can extract plaintext credentials from the `workflow-controller` logs and gain access to the artifact repository. This can lead to: - Data exfiltration – theft of sensitive or proprietary artifacts - Data tampering – modification of workflows or artifacts - Data destruction – deletion of stored artifacts, leading to potential loss of critical data or pipeline failure
