Zarf is an Airgap Native Packager Manager for Kubernetes. From version 0.54.0 to before version 0.73.1, a path traversal vulnerability in archive extraction allows a specifically crafted Zarf package to create symlinks pointing outside the destination directory, enabling arbitrary file read or write on the system processing the package.

lfprojects zarf UPGRADE

Affected: >= 0.54.0 and < 0.73.1

Fixed in: 0.73.1

Safe to downgrade to: a release before 0.54.0

1. Check installed version

apt-cache policy zarf || rpm -q zarf || zarf --version

2. UPGRADE to 0.73.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade zarf

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade zarf

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 0.54.0 (Debian / Ubuntu)

apt-cache madison zarf sudo apt install zarf=<VERSION_BEFORE_0.54.0> sudo apt-mark hold zarf

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

dnf --showduplicates list zarf sudo dnf downgrade zarf-<VERSION_BEFORE_0.54.0> sudo dnf versionlock add zarf

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.
