"The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the SVD-2026-0206 advisory.

  - In Splunk Enterprise versions below 10.0.2, 10.0.3, 9.4.8, and 9.3.9, a low-privileged user who does not
    hold the admin Splunk role could access the Splunk Monitoring Console App endpoints due to an improper
    access control. This could lead to a sensitive information disclosure. The Monitoring Console app is a
    bundled app that comes with Splunk Enterprise. It is not available for download on SplunkBase, and is not
    installed on Splunk Cloud Platform instances. This vulnerability does not affect Cloud Monitoring Console.
    (CVE-2026-20141)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
