CVE-2026-47190
Description
A flaw was found in the Cluster API Provider Metal3 IP Address Manager (IPAM) controller. The controller's ClusterRole granted excessive permissions, allowing full create, read, update, and delete (CRUD) access to core/v1 Secrets. If the controller pod were compromised, an attacker could leverage these permissions to read, modify, or delete sensitive data within the namespace. This could lead to the exposure of credentials and other sensitive information.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
