CVE-2026-71201
Description
A flaw was found in OpenStack Ironic. A project reader can exploit this vulnerability by sending a specially crafted request to the Ironic service. This allows the reader to access Portgroups that are assigned to Nodes belonging to or leased by other projects, leading to unauthorized information disclosure.
Statement
This flaw has a moderate impact as OpenStack Ironic contains an authorization flaw in the Portgroups listing API. When a project-scoped reader lists portgroups by shard name, the service fails to apply the per-project ownership filter that it correctly applies on other listing paths, allowing the reader to enumerate portgroups belonging to nodes owned or leased by other projects. Exploitation requires valid project-reader credentials and knowledge of a target shard name, and discloses only portgroup metadata (no modification or availability impact), so the severity is limited to information disclosure across project boundaries. Red Hat OpenShift's baremetal (metal3) deployment runs Ironic as a single-tenant control-plane service and does not expose the multi-project reader RBAC path required for exploitation.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
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.

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
Access control checks for specific user data or functionality can be bypassed.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Horizontal escalation of privilege is possible (one user can view/modify information of another user).
Access Control
Technical Impact: Gain Privileges or Assume Identity
Vertical escalation of privilege is possible if the user-controlled key is actually a flag that indicates administrator status, allowing the attacker to gain administrative access.
