The affected instance requires a restart to restore service.\nThe vulnerability is possible because the endpoint does not limit resource use when it processes response field selections.\nFor more information see Endpoints reference list (https://help.splunk.com/en/splunk-enterprise/rest-api-reference/10.4/introduction/endpoints-reference-list) and About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) in the Splunk documentation.","state":0,"publishedAt":"2026-10-21T22:51:51.849+00:00","modifiedAt":"2026-10-22T13:37:48.707+00:00","affected":[{"ecosystem":"Vendor product","name":"Splunk Enterprise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Splunk Enterprise\",\n                    \"vendor\": \"Splunk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"10.4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.4.4\"\n                        },\n                        {\n                            \"version\": \"10.2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.2.8\"\n                        },\n                        {\n                            \"version\": \"10.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.0.11\"\n                        },\n                        {\n                            \"version\": \"9.4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"9.4.16\"\n                        }\n                    ],\n                    \"modules\": [\n                        \"REST API\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://advisory.splunk.com/advisories/SVD-2026-1007"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76289","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76289","identifiers":["CVE-2026-76289"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
