CVE-2026-47190 metal3-io CVE debrief

CVE-2026-47190 is a vulnerability in IPAM, the IP address Manager for Cluster API Provider Metal3. The IPAM controller's ClusterRole granted excessive CRUD (create, delete, get, list, patch, update, watch) permissions on core/v1 Secrets. These excessive permissions could allow an attacker to read, modify, or delete Secrets in the namespace if the controller pod were compromised, potentially exposing credentials and other sensitive data. The issue was patched in versions 1.11.7, 1.12.4, and 1.13.0.
