This vulnerability resides within the \u003ccode\u003eexec_openstack\u003c/code\u003e function of the \u003ccode\u003eserver.py\u003c/code\u003e file. Due to insufficient input sanitization, a remote attacker can inject arbitrary OS commands. The exploit is publicly available, increasing the risk of exploitation. The vendor utilizes rolling releases, so specific affected versions are difficult to pinpoint. The project has been notified of the vulnerability but has not yet addressed it.
