Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14 contain a vulnerability where users with a role that includes the high-privilege list_search_head_clustering capability can send read requests to Search Head Cluster member control endpoints and inadvertently change cluster state. This occurs because these endpoints do not require a state-changing HTTP request method before applying read-only authorization, potentially leading to denial of service.
AI Analysis
Technical Summary
CVE-2026-76348 affects Splunk Enterprise versions prior to 10.4.2, 10.2.6, 10.0.9, and 9.4.14. The vulnerability arises from insufficient enforcement of HTTP request methods on Search Head Cluster member control endpoints. Specifically, users with the list_search_head_clustering capability can send read requests that improperly trigger state changes in the cluster, resulting in a denial of service condition. This is due to the endpoints not requiring a state-changing HTTP request type before applying read-only authorization checks.
Potential Impact
An attacker with a Splunk role containing the list_search_head_clustering capability can cause denial of service by changing the cluster state through read requests to control endpoints. There is no confidentiality impact, but integrity and availability are affected. The CVSS v3.1 base score is 3.8 (low severity), reflecting low impact and requiring high privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, restrict roles with the list_search_head_clustering capability to trusted users only to minimize risk.
