  - In Splunk Enterprise versions below 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions below
    9.3.2411.108, 9.3.2408.118 and 9.2.2406.123, a low privilege user that does not hold the admin or
    power Splunk roles could perform an extensible markup language (XML) external entity (XXE) injection
    through the dashboard tab label field. The XXE injection has the potential to cause denial of service
    (DoS) attacks. (CVE-2025-20369)
