      "title": "Denial of Service (DoS) in the Discover Splunk Observability Cloud app for Splunk Enterprise",
      "summary": "In Splunk Enterprise versions below 10.4.3, 10.2.7, and 10.0.10, a low-privileged user that does not hold the \"admin\" or \"power\" Splunk roles could cause a denial of service against a Representational State Transfer (REST) API endpoint in the Discover Splunk Observability Cloud app. The vulnerability is possible because the app uses an inefficient regular expression to validate input submitted through the endpoint. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access), Splunk Observability Cloud previews (https://help.splunk.com/en/splunk-enterprise/search/search-manual/10.4/observability/splunk-observability-cloud-previews), and restmap.conf (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/configuration-file-reference/10.4.0-configuration-file-reference/restmap.conf) in the Splunk documentation.\n\nSplunk Enterprise versions 9.4.x are not affected.",
