Noobaa-core: noobaa-core: os command injection in cluster_internal_api.set_hostname_internal
An OS command injection flaw was found in the set_hostname_internal function of NooBaa's cluster_internal_api.

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.
