Routine

MEDIUM 4.4UPGRADE

CVE-2026-47190 is a medium-severity flaw (CVSS 4.4) affecting ip-address-manager. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

IPAM is the IP address Manager for Cluster API Provider Metal3. Prior to versions 1.11.7, 1.12.4, and 1.13.0, the IPAM controller's ClusterRole granted full CRUD permissions (create, delete, get, list, patch, update, watch) on core/v1 Secrets. The controller never accesses Secrets during normal operation. If the controller pod were compromised (e.g. via supply chain attack or container escape), an attacker could leverage these excessive permissio

Safe to downgrade to: a release before 1.11.0

1. Check installed version

apt-cache policy ip-address-manager || rpm -q ip-address-manager || ip-address-manager --version

2. UPGRADE to 1.11.7 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ip-address-manager

sudo dnf upgrade ip-address-manager

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 1.11.0 (Debian / Ubuntu)

apt-cache madison ip-address-manager sudo apt install ip-address-manager=<VERSION_BEFORE_1.11.0> sudo apt-mark hold ip-address-manager

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

dnf --showduplicates list ip-address-manager sudo dnf downgrade ip-address-manager-<VERSION_BEFORE_1.11.0> sudo dnf versionlock add ip-address-manager

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.
