medium Nessus Plugin ID 299408

Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

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-2026-0209 advisory.

 - In Splunk Enterprise versions below 10.2.0, 10.0.2, 9.4.7, 9.3.8, and 9.2.11, and Splunk Cloud Platform versions below 10.2.2510.0, 10.1.2507.11, 10.0.2503.9, and 9.3.2411.120, a user of a Splunk Search Head Cluster (SHC) deployment who holds a role with access to the Splunk _internal index could view the Security Assertion Markup Language (SAML) configurations for Attribute query requests (AQRs) or Authentication extensions in plain text within the conf.log file, depending on which feature is configured. For more information, see: Specify searchable indexes for a roleConfigure authentication extensions to interface with your SAML identity provider (CVE-2026-20144)

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

Solution

Upgrade Splunk Enterprise to versions 10.2.0, 10.0.2, 9.4.7, 9.3.8, 9.2.11, or higher.
Splunk is actively monitoring and patching Splunk Cloud Platform instances.
