{"id":"CVE-2026-76304","kind":"vulnerability","aliases":["CVE-2026-76304"],"related":[],"title":"Splunk SOAR: low-privilege users can download Automation Broker Docker config","description":"In Splunk SOAR versions below 8.7.0, an authenticated user who does not hold a role with permission to edit Automation Brokers could download the Splunk SOAR Automation Broker Docker Compose configuration file. The file contains the Uniform Resource Locator (URL) of the Splunk SOAR instance, the container image location, and the Splunk SOAR Automation Broker version.\nThe vulnerability is possible because Splunk SOAR returns the configuration file without enforcing the Automation Broker edit permission.\nFor more information see Install Splunk Automation Broker on a Docker host (https://help.splunk.com/en/splunk-soar/splunk-automation-broker/install-and-create-classic-splunk-soar-automation-brokers/install-splunk-automation-broker-on-a-docker-host) and Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) in the Splunk documentation.","summary":"Splunk SOAR versions below 8.7.0 return the Automation Broker Docker Compose file to authenticated users who lack permission to edit brokers.
