CVE-2026-76323Network attack vector

User-context SPL execution via search identifier

Published Aug 19, 2026 · Updated Aug 21, 2026

Improper input validation in Splunk Enterprise before 10.4.2, 10.2.6, 10.0.9, and 9.4.14 allows attackers to run SPL via a crafted link. The Job Details dashboard places a caller-supplied search identifier into SPL searches without correctly neutralizing it, letting injected risky commands execute in the opened view. Exploitation requires a low-privileged authenticated user to phish another authenticated user into opening the link, after which the injected SPL inherits that user's data access and write permissions.
