CVE-2026-76255Network attack vector

Cross-user SPL execution via Data Model Editor

Published Aug 19, 2026 · Updated Aug 21, 2026

SPL injection in Splunk Enterprise before 10.4.1, 10.2.6, 10.0.8, and 9.4.13 allows remote authenticated users to run arbitrary SPL via the Data Model Editor. When the editor runs the base search for auto-extracted fields, Splunk Web does not apply risky-command safeguards, so a crafted request can dispatch commands under the affected user's existing permissions. Exploitation requires a non-admin, non-power user to phish another authenticated user into initiating the browser request, and impact is limited to data access and actions allowed by the affected user's role.
