CVE-2026-47359

Name of the Vulnerable Software and Affected Versions Apache CloudStack versions 4.20.0.0 through 4.20.3.0 Apache CloudStack versions 4.21.0.0 through 4.22.1.0

Description An OS Command Injection issue exists in the NAS backup provider plugin. The 'addBackupRepository' and 'updateBackupRepository' API endpoints 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 a backup restore is performed by any account.

Recommendations Upgrade versions 4.20.0.0 through 4.20.3.0 to 4.20.3.1 or later. Upgrade versions 4.21.0.0 through 4.22.1.0 to 4.22.1.1 or later.
