vulnerability as referenced in the SVD-2023-0206 advisory.

  - In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the search_listener' parameter in a search
    allows for a blind server-side request forgery (SSRF) by an authenticated user. The initiator of the
    request cannot see the response without the presence of an additional vulnerability within the
    environment. (CVE-2023-22936)

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