CVE-2022-36035 is a high-severity flaw (CVSS 7.7) affecting flux2. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy. Flux CLI allows users to deploy Flux components into a Kubernetes cluster via command-line. The vulnerability allows other applications to replace the Flux deployment information with arbitrary content which is deployed into the target Kubernetes cluster instead. Th

fluxcd flux2 UPGRADE

Affected: >= 0.21.0 and < 0.32.0

Fixed in: 0.32.0

Safe to downgrade to: a release before 0.21.0

1. Check installed version

apt-cache policy flux2 || rpm -q flux2 || flux2 --version

2. UPGRADE to 0.32.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade flux2

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade flux2

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 0.21.0 (Debian / Ubuntu)

apt-cache madison flux2 sudo apt install flux2=<VERSION_BEFORE_0.21.0> sudo apt-mark hold flux2

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

dnf --showduplicates list flux2 sudo dnf downgrade flux2-<VERSION_BEFORE_0.21.0> sudo dnf versionlock add flux2

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.
