## Description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who has an embedded report token could download the associated search job dispatch archive, recover session material, and use it to access all relevant data available to the report owner and affect system integrity, including by performing administrative actions when the owner holds the "admin" Splunk role. The vulnerability is possible because embedded report access does not block Representational State Transfer (REST) API dispatch archive download requests. For more information see Additional configuration for embedded reports (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/9.1/report-management/additional-configuration-for-embedded-reports) 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.
