Vulnerability from csaf_redhat - Published: 2026-07-15 09:55 - Updated: 2026-07-15 12:49Summary
Red Hat Security Advisory: Red Hat OpenStack Services on OpenShift 18.0 (openstack-ironic) security update
Severity
Important
Notes
Topic: An update for openstack-ironic is now available for Red Hat OpenStack
Services on OpenShift 18.0 (Antelope).
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
Details: Ironic is a project which aims to provision bare metal (as opposed to
virtual) machines by leveraging common technologies such as PXE boot and
IPMI to cover a wide range of hardware, while supporting pluggable drivers
to allow vendor-specific functionality to be added.
Security Fix(es):
* Ironic: OpenStack Ironic: Information disclosure via credential
forwarding during mold import (CVE-2026-42997)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page listed in the References section.

A flaw was found in OpenStack Ironic. During the import process, a user invoking molds can request that authorization credentials be sent to a remote endpoint. This can lead to the disclosure of a time-limited Keystone token, which grants access to OpenStack services Ironic is authorized for, or basic credentials configured for molds storage. This information disclosure could allow an attacker to gain unauthorized access to other OpenStack services.
