GHSA-XC7X-4VW8-2652

Vulnerability from github – Published: 2026-09-28 15:31 – Updated: 2026-09-28 15:31

Details

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.

Severity

7.2 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
