CVE-2026-20296
EUVD-2026-4473715.07.2026, 18:16
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.
