## Description

In Splunk SOAR versions below 8.7.0, an authenticated user could change the Enterprise Security edition through the Representational State Transfer (REST) API and cause Splunk SOAR to apply the license change. The vulnerability is possible because Splunk SOAR authenticates requests to manage the Enterprise Security edition but does not authorize the caller before it applies the license change. For 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/8.7.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises), Obtain and configure a Splunk SOAR (On-premises) license (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.7.0/configure-your-companys-settings-in-splunk-soar-on-premises/obtain-and-configure-a-splunk-soar-on-premises-license), and Integration of Splunk SOAR with Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/administer/8.7/automation-with-playbooks/integration-of-splunk-soar-with-splunk-enterprise-security) in the Splunk documentation.
