The unauthenticated user should not be able to exploit the vulnerability at will.\nFor more information see Using the REST API reference for Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/8.5.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises) in the Splunk documentation.","state":0,"publishedAt":"2026-10-21T22:52:12.496+00:00","modifiedAt":"2026-10-28T02:08:31.206+00:00","affected":[{"ecosystem":"Vendor product","name":"Splunk SOAR","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Splunk SOAR\",\n                    \"vendor\": \"Splunk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"8.7.0\"\n                        }\n                    ],\n                    \"modules\": [\n                        \"REST API\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9,"severity":"MEDIUM"}],"references":["https://advisory.splunk.com/advisories/SVD-2026-1010"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76406","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76406","identifiers":["CVE-2026-76406"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
