What it is

In Splunk SOAR versions below 8.7.0, an authenticated user who does not hold a role with permission to view apps could download an archive of an installed app. This could expose all data in the app archive, including proprietary source code and sensitive information.

The vulnerability is possible because Splunk SOAR does not verify permission to view apps before it returns the app archive.

For more information see Export or import an app (https://help.splunk.com/en/splunk-soar/soar-on-premises/develop-apps/8.4.0/develop-an-app-using-the-splunk-soar-app-wizard/export-or-import-an-app) 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.
