CVE-2026-20296
SPL Command Safeguards Bypass through Cross-Site Request Forgery (CSRF) in Deployment Server in Splunk Enterprise
Description

In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, and 9.4.13, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.7, 10.3.2512.16, 10.2.2510.18, and 10.1.2507.24, an attacker could trick a user that holds a role with the `list_deployment_server` capability into running arbitrary Search Processing Language (SPL) searches on their behalf as `splunk-system-user`, allowing for access to stored credentials and indexed data.<br><br>The vulnerability is possible because Deployment Server endpoints in Splunk Web do not validate Cross-Site Request Forgery (CSRF) tokens on GET requests, and caller-supplied input is not correctly neutralized before it is placed into an SPL search.
