"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-2026-0303 advisory.

  - In Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.9, and 9.3.10, and Splunk Cloud Platform versions
    below 10.2.2510.5, 10.1.2507.16, 10.0.2503.11, and 9.3.2411.123, a low-privileged user that does not hold
    the admin or power Splunk roles could access the `/splunkd/__raw/servicesNS/-/-/configs/conf-
    passwords` REST API endpoint, which exposes the hashed or plaintext password values that are stored in the
    passwords.conf configuration file due to improper access control. This vulnerability could allow for the
    unauthorized disclosure of sensitive credentials. (CVE-2026-20164)

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