CVE-2026-48681
Description
A flaw was found in OpenStack Ironic (before 35.0.2). A directory traversal vulnerability during deployment allows an attacker to overwrite files on the system when a crafted ISO image is used. This can compromise confidentiality and integrity of files on the deployment target.
Statement
OpenStack Ironic is vulnerable to directory traversal during node deployment when processing a crafted ISO image, allowing file overwrite on the target system. A remote attacker with high privileges who can initiate deployments with attacker-controlled ISO content could read or modify files (confidentiality and integrity impact). Affects OpenStack 16.2, 17.1, 18.0, and OpenShift-embedded openstack-ironic RPM streams.
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.
