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-2026-0402 advisory.

 - In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.10, and 9.3.11, and Splunk Cloud Platform versions below 10.4.2603.0, 10.3.2512.6, 10.2.2510.10, 10.1.2507.19, 10.0.2503.13, and 9.3.2411.127, a low- privileged user that does not hold the `admin` or `power` Splunk roles, has write permission on the app, and does not hold the high-privilege capability `accelerate_datamodel`, could turn on or off Data Model Acceleration due to improper access control. (CVE-2026-20203)

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 10.2.2, 10.0.5, 9.4.10, 9.3.11, or higher. Splunk is actively monitoring and patching Splunk Cloud Platform instances.
