CVE-2026-76330Network attack vector

Authenticated-session SPL execution via forwarder filters

Published Aug 19, 2026 · Updated Aug 21, 2026

SPL injection in Splunk Enterprise Monitoring Console before 10.4.2, 10.2.6, 10.0.9, and 9.4.14 allows remote attackers to run SPL via a crafted link. Monitoring Console uses insufficiently validated forwarder filter data to build forwarder dashboard searches, so crafted link parameters can inject attacker-controlled Search Processing Language that executes with the opened session's permissions. Exploitation requires phishing an authenticated user into opening the Monitoring Console link in Splunk Web, after which injected searches can read data and perform permitted actions as that user.
