What is CVE-2026-86330?

An OS command injection vulnerability exists in the set_hostname_internal function of NooBaa's cluster_internal_api. This component manages the Multi-Cloud Object Gateway in the OpenShift Data Foundation. The issue arises from inadequate sanitization of the hostname parameter, allowing an authenticated attacker with administrative privileges to inject shell metacharacters through a crafted hostname. This could lead to the execution of arbitrary commands on the host system with NooBaa process privileges, posing a significant security risk.
