{"apiVersion":"1.0","identifier":"CVE-2026-47359","description":"Improper Neutralization of Special Elements used in an OS Command (-OS Command Injection-) vulnerability in Apache CloudStack-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. 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. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.","publishedAt":"2026-08-21T09:16:38","lastModifiedAt":"2026-08-27T00:06:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47359","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.01103,"riskScore":0.97,"affectedProduct":"Apache CloudStack","affectedVersions":">=4.20.0.0,<=4.20.3.0,>=4.21.0.0,<=4.22.1.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-47359","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-47359","en":"https://www.redsauce.net/en/cves/CVE-2026-47359","fr":"https://www.redsauce.net/fr/cves/CVE-2026-47359","pt":"https://www.redsauce.net/pt/cves/CVE-2026-47359","de":"https://www.redsauce.net/de/cves/CVE-2026-47359","sk":"https://www.redsauce.net/sk/cves/CVE-2026-47359","el":"https://www.redsauce.net/el/cves/CVE-2026-47359"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-47359"}}
