CVE-2026-76348: Splunk

Low severity, CVSS 3.8. EPSS: 0.3% chance of exploitation in the next 30 days.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds a Splunk role that contains the high-privilege list_search_head_clustering capability could send a read request to Search Head Cluster member control endpoints and change cluster state, which could allow for a denial of service. The vulnerability is possible because the Search Head Cluster member control endpoints do not require a state-changing Hypertext Transfer Protocol (HTTP) request type before they apply read-only authorization.

Affected products

• Splunk Splunk: from 9.4.0, before 9.4.14 (fixed in 9.4.14); from 10.0.0, before 10.0.9 (fixed in 10.0.9); from 10.2.0, before 10.2.6 (fixed in 10.2.6); from 10.4.0, before 10.4.2 (fixed in 10.4.2)
