CVE-2026-47359

*** Pendiente de traducción *** Improper Neutralization of Special Elements used in an OS Command (&amp;#39;OS Command Injection&amp;#39;) vulnerability in Apache CloudStack&amp;#39;s NAS backup provider plugin. The addBackupRepository API (available since 4.20.0.0) and updateBackupRepository API (introduced in 4.22.0.0) accept unsanitized command options for the backup repository. A malicious operator account can exploit this to inject arbitrary commands that execute on the KVM hypervisor host when any account subsequently performs a backup restore.<br /> <br /> This issue affects Apache CloudStack: from 4.20.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.<br /> <br /> Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
