In Splunk Enterprise versions below 10.4.3, 10.2.7, and 10.0.10, a user that holds a role with the edit_spl2_module_permissions capability could use the affected Representational State Transfer (REST) API to access permission grants for SPL2 modules that the user does not have permission to view. The vulnerability is possible because Splunk Enterprise does not verify that the user can read the requested app before the affected REST API returns SPL2 module permission grants. For more information see Module permissions (https://help.splunk.com/en/splunk-enterprise/search/spl2-search-manual/modules-statements-and-views/module-permissions) and Manage SPL2 modules (https://help.splunk.com/en/splunk-enterprise/search/spl2-search-manual/multiple-searches-in-an-spl2-module/manage-spl2-modules) in the Splunk documentation. Splunk Enterprise versions 9.4.x are not affected.
