CVE-2026-20296Network attack vector

Arbitrary SPL execution via tokenless GET requests

Published Jul 15, 2026 · Updated Jul 15, 2026

Cross-site request forgery in Splunk Enterprise and Splunk Cloud Platform allows remote attackers to run arbitrary SPL searches. Deployment Server endpoints accept GET requests without validating CSRF tokens and place caller-controlled input into an SPL search without correct neutralization. Exploitation requires a tricked user whose role has list_deployment_server; the resulting search runs as splunk-system-user and can expose stored credentials and indexed data.
