CVE-2026-76289
Denial of Service (DoS) through the REST API in Splunk Enterprise
Published Oct 21, 2026
CVSS 3.1 · 6.5 Medium
EPSS < 1%
KEV · Not listed
Description
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user who does not hold the "admin" or "power" Splunk roles could make the Splunk Enterprise instance unavailable to other users by sending a request to the Representational State Transfer (REST) API endpoint for lookup table files. The affected instance requires a restart to restore service.
The vulnerability is possible because the endpoint does not limit resource use when it processes response field selections.
