{"id":"CVE-2026-61422","summary":"Apache CloudStack: Authenticated pre-validation SSRF in registerTemplate","details":"Authenticated pre-validation SSRF vulnerability in Apache CloudStack's template and ISO registration functionality.\n\nWhen 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.\n\nUsers are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.","modified":"2026-08-28T03:47:07.218669671Z","published":"2026-08-21T08:24:38.323Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61422.json","unresolved_ranges":[{"extracted_events":[{"introduced":"4.20.3.0"},{"last_affected":"4.20.3.0"},{"introduced":"4.21.0.0"},{"last_affected":"4.22.1.0"}],"source":"AFFECTED_FIELD"},{"extracted_events":[{"introduced":"4.21.0.0"},{"fixed":"4.22.1.0"}],"source":"DESCRIPTION"}],"cna_assigner":"apache","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61422.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/g6cwddtjrwbh1d56wjz4cfp3fzfm4kbc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61422"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/cloudstack","events":[{"introduced":"c8599040b4756034c7105806a53d2c99eb7ea0fe"},{"last_affected":"c8599040b4756034c7105806a53d2c99eb7ea0fe"}],"database_specific":{"extracted_events":[{"introduced":"4.20.3.0"},{"last_affected":"4.20.3.0"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:apache:cloudstack:4.20.3.0:*:*:*:*:*:*:*"}}],"versions":["4.20.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61422.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
