In Splunk SOAR versions below 8.6.0, a user with a valid Splunk SOAR account could use Representational State Transfer (REST) API filtering on playbook runs to recover session tokens that compromise all data available to the affected user. The information disclosure is possible because Splunk SOAR does not block REST API filters from matching values that responses otherwise hide. For more information see REST Run Playbook (https://help.splunk.com/en/splunk-soar/soar-cloud/rest-api-reference/run-playbook-endpoints/rest-run-playbook) in the Splunk documentation.
