CVE-2026-76254Network attack vector

Arbitrary SPL execution via dataset name injection

Published Aug 19, 2026 · Updated Aug 21, 2026

SPL injection in Splunk Enterprise before 10.4.2, 10.2.6, 10.0.9, 9.4.14, and 9.3.14 allows remote attackers to run searches as another user via a crafted link. Dataset Explorer builds SPL from an untrusted dataset name without validation or escaping and omits the risky-command safeguards normally applied to those generated searches. Exploitation requires phishing a user into opening the link in Splunk Web, after which the injected pipeline runs with that user's data access and change permissions and can also affect availability.
