CVE-2022-39272 is a medium-severity flaw (CVSS 5.0) affecting flux2, helm-controller, image-automation-controller. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Flux is an open and extensible continuous delivery solution for Kubernetes. Versions prior to 0.35.0 are subject to a Denial of Service. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed. This issue is patched in ver

fluxcd flux2 UPGRADE
Affected: >= 0.1.0 and < 0.35.0
Fixed in: 0.35.0
Safe to downgrade to: a release before 0.1.0
1. Check installed version
apt-cache policy flux2 || rpm -q flux2 || flux2 --version
2. UPGRADE to 0.35.0 (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 0.1.0 (Debian / Ubuntu)
apt-cache madison flux2
sudo apt install flux2=<VERSION_BEFORE_0.1.0>
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_0.1.0>
sudo dnf versionlock add flux2
