Vulnerability from github – Published: 2026-07-15 18:31 – Updated: 2026-07-15 18:31

Details

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.

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.

Severity

8.3 (High)
