CVE-2026-76348
Last modified
CVE-2026-76348 is a low-severity vulnerability rated 3.8/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
