## 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 dispatch archive for an embedded report search job and use exposed session material to access all relevant data and affect system integrity on the Splunk platform instance. The vulnerability is possible because the embedded report authorization flow does not block dispatch archive download requests before Splunk Enterprise begins sending the archive to the requester. For more information see Additional configuration for embedded reports (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/10.4/report-management/additional-configuration-for-embedded-reports) and Embed scheduled reports (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/10.4/report-management/embed-scheduled-reports) in the Splunk documentation.
