CVE-2026-42295 is a medium-severity flaw (CVSS 4.9) affecting argo workflows. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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

argoproj argo workflows UPGRADE

Affected: >= 4.0.0 and < 4.0.5

Fixed in: 4.0.5

Safe to downgrade to: a release before 4.0.0

1. Check installed version

apt-cache policy argo-workflows || rpm -q argo-workflows || argo-workflows --version

2. UPGRADE to 4.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade argo-workflows

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade argo-workflows

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 4.0.0 (Debian / Ubuntu)

apt-cache madison argo-workflows sudo apt install argo-workflows=<VERSION_BEFORE_4.0.0> sudo apt-mark hold argo-workflows

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list argo-workflows sudo dnf downgrade argo-workflows-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add argo-workflows

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
