{"apiVersion":"1.0","identifier":"CVE-2026-61422","description":"Authenticated pre-validation SSRF vulnerability in Apache CloudStack-s template and ISO registration functionality. When registering a template or ISO, CloudStack makes a live HTTP HEAD/GET call to determine file size for secondary storage usage-limit checks, and this happens before URL validation is performed. However, this does not pose a malicious template or ISO registration risk, as URL validation still occurs prior to the actual download by the Secondary Storage VM.This issue affects Apache CloudStack: in 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":"2026-08-21T09:16:39","lastModifiedAt":"2026-08-27T14:37:55","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61422","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","epssProbability":0.00238,"riskScore":0.44,"affectedProduct":"Apache CloudStack","affectedVersions":"==4.20.3.0,>=4.21.0.0,<4.22.1.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-61422","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-61422","en":"https://www.redsauce.net/en/cves/CVE-2026-61422","fr":"https://www.redsauce.net/fr/cves/CVE-2026-61422","pt":"https://www.redsauce.net/pt/cves/CVE-2026-61422","de":"https://www.redsauce.net/de/cves/CVE-2026-61422","sk":"https://www.redsauce.net/sk/cves/CVE-2026-61422","el":"https://www.redsauce.net/el/cves/CVE-2026-61422"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-61422"}}
