CVE-2026-47190

Workarounds

Manually remove the Secrets resource entry from the metal3-ipam-controller-manager-role ClusterRole:

# Remove this entire block from the ClusterRole
- apiGroups:
  - ""
  resources:
  - secrets
  verbs:
  - create
  - delete
  - get
  - list
  - patch
  - update
  - watch

• https://github.com/metal3-io/ip-address-manager/pull/1356 (backport to release-1.12)

IPAM is the IP address Manager for Cluster API Provider Metal3. 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 permissions to read, modify, or delete Secrets in the namespace, potentially exposing credentials and other sensitive data.

All users running ip-address-manager versions prior to the patched releases are affected.

CVE-2026-47190 has a CVSS score of 4.4 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.11.7, 1.12.4); upgrading removes the vulnerable code path.

Fixed in:

• v1.11.7
• v1.12.4
• v1.13.0

Users should upgrade to the patched version for their release branch.

1. What is CVE-2026-47190? CVE-2026-47190 is a medium-severity security vulnerability in github.com/metal3-io/ip-address-manager (go), affecting versions <= 1.11.6. It is fixed in 1.11.7, 1.12.4.
2. How severe is CVE-2026-47190? CVE-2026-47190 has a CVSS score of 4.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/metal3-io/ip-address-manager are affected by CVE-2026-47190? github.com/metal3-io/ip-address-manager (go) versions <= 1.11.6 is affected.
4. Is there a fix for CVE-2026-47190? Yes. CVE-2026-47190 is fixed in 1.11.7, 1.12.4. Upgrade to this version or later.
5. Is CVE-2026-47190 exploitable, and should I be worried? Whether CVE-2026-47190 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-47190 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-47190?
   • Upgrade github.com/metal3-io/ip-address-manager to 1.11.7 or later
   • Upgrade github.com/metal3-io/ip-address-manager to 1.12.4 or later
