Splunk Enterprise 9.4.0 < 9.4.15, 10.0.0 < 10.0.10, 10.2.0 < 10.2.6, 10.4.0 < 10.4.2 (SVD-2026-1001)

medium Nessus Plugin ID 364459

Synopsis

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

Description

The version of Splunk Enterprise installed on the remote host is 9.4.x prior to 9.4.15, 10.0.x prior to 10.0.10, 10.2.x prior to 10.2.6, or 10.4.x prior to 10.4.2. It is, therefore, affected by an improper authorization vulnerability as referenced in the SVD-2026-1001 advisory. A user who does not hold the admin or power roles could create or edit scripted lookup definitions through raw configuration endpoints, because raw transforms configuration write paths do not apply external lookup capability checks before saving scripted lookup settings. (CVE-2026-76264)

Note that this plugin only runs when 'Report paranoia' is set to 'Paranoid', because the fix also requires a configuration change that Nessus cannot check.

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 version 9.4.15, 10.0.10, 10.2.6, 10.4.2, or later, then set scripted_lookup_raw_write_enforcement = block under the [lookup] stanza of limits.conf and restart Splunk Enterprise.
