CVE-2026-76347
PUBLISHED
CVSS 5.4 MEDIUM
Reported by cisco · Published August 19, 2026
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, a user who does not hold the "admin" or "power" Splunk roles could use Server-Side Request Forgery (SSRF) in report notifications to send system-authenticated requests to internal Splunk services, which could allow for changes to Search Head Cluster state and a denial of service. The vulnerability is possible because Splunk Secure Gateway does not validate report notification path values before it sends internal requests.
