If the inferred token grants administrative access, that user could gain administrative access to the Splunk SOAR instance.\nThe vulnerability is possible because the REST API accepts caller-controlled query filters on sensitive user record fields.\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/7.1.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises), Query for Data (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/7.1.0/using-the-splunk-soar-rest-api/query-for-data), and Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/6.4.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) in the Splunk documentation.","published":"2026-10-21T23:17:29.000Z","lastModified":"2026-10-23T15:17:35.000Z","status":"Undergoing Analysis","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.00398,"percentile":0.33746,"date":"2026-10-26","history":[{"date":"2026-10-22","score":0.00317,"percentile":0.23346}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%).
