With this access, the first user could access data and make changes that the user who opened the app documentation could make.\nThe vulnerability is possible because Splunk SOAR does not sanitize app documentation content before it displays that content.\nThe vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user that holds a role with the install_apps capability should not be able to exploit the vulnerability at will.\nFor more information see Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/7.1.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) and Add and configure apps and assets to provide actions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.6.0/manage-your-splunk-soar-on-premises-apps-and-assets/add-and-configure-apps-and-assets-to-provide-actions-in-splunk-soar-on-premises) in the Splunk documentation.","state":0,"publishedAt":"2026-10-21T22:52:04.809+00:00","modifiedAt":"2026-10-23T15:08:29.705+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                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:N","score":5.7,"severity":"MEDIUM"}],"references":["https://advisory.splunk.com/advisories/SVD-2026-1010"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76303","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76303","identifiers":["CVE-2026-76303"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
