MEDIUM 5.0UPGRADE

CVE-2026-27111 is a medium-severity flaw (CVSS 5.0) affecting kargo. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

akuity kargo UPGRADE

Affected: >= 1.9.0 and < 1.9.3

Fixed in: 1.9.3

Safe to downgrade to: a release before 1.9.0

1. Check installed version

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

2. UPGRADE to 1.9.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade kargo

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 1.9.0 (Debian / Ubuntu)

apt-cache madison kargo sudo apt install kargo=<VERSION_BEFORE_1.9.0> sudo apt-mark hold kargo

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

dnf --showduplicates list kargo sudo dnf downgrade kargo-<VERSION_BEFORE_1.9.0> sudo dnf versionlock add kargo

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.
