RCE in Red Hat Openshift Data Foundation 4
CVE-2026-86330
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.
