- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- cisco rates this medium
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 10.4.4, 10.2.8, 10.0.11, 9.4.16
- Published: 2026-10-21 · Updated: 2026-10-22

## Affected

- Splunk Splunk Enterprise: from 10.4, fixed in 10.4.4; from 10.2, fixed in 10.2.8; from 10.0, fixed in 10.0.11; from 9.4, fixed in 9.4.16

## Description

In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user who does not hold the "admin" or "power" Splunk roles could move field extractions or field transformations to apps for which the user does not have read access. The vulnerability is possible because the Representational State Transfer (REST) API does not validate destination app access before it processes field extraction and field transformation move operations. For more information see Use the Field extractions page (https://help.splunk.com/en/splunk-enterprise/manage-knowledge-objects/knowledge-management-manual/10.6/use-the-settings-pages-for-field-extractions-in-splunk-web/use-the-field-extractions-page) and Manage knowledge object permissions (https://help.splunk.com/en/splunk-enterprise/manage-knowledge-objects/knowledge-management-manual/10.6/get-started-with-knowledge-objects/manage-knowledge-object-permissions) in the Splunk documentation.
