Noobaa-core: noobaa-core: os command injection in cluster_internal_api.set_hostname_internal

Published Sep 28, 2026 CVSS 3.1 · 7.2 High EPSS 2.2% KEV · Not listed
Description
An OS command injection flaw was found in the set_hostname_internal function of NooBaa's cluster_internal_api. This component is responsible for managing the Multi-Cloud Object Gateway in OpenShift Data Foundation. The vulnerability occurs because the hostname parameter is passed directly to a shell command without proper sanitization. An authenticated attacker with administrative privileges can provide a specially crafted hostname containing shell metacharacters to execute arbitrary commands on the host system with the privileges of the NooBaa process.
