The vulnerability is possible because the Linux package maintainer script trusts existing Splunk Enterprise installation content when it performs upgrade operations with root privileges. The vulnerability requires an affected Linux package upgrade to occur after the local user modifies the installation. The local user should not be able to elevate privileges at will.","state":0,"publishedAt":"2026-10-07T20:46:29.794+00:00","modifiedAt":"2026-10-09T03:55:28.884+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\": \"10.4.3\"\n                        },\n                        {\n                            \"version\": \"10.2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.2.7\"\n                        },\n                        {\n                            \"version\": \"10.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.0.10\"\n                        },\n                        {\n                            \"version\": \"9.4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"9.4.15\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H","score":7.7,"severity":"HIGH"}],"references":["https://advisory.splunk.com/advisories/SVD-2026-1001"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76266","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76266","identifiers":["CVE-2026-76266"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
