- Follow the official vendor advisory
- Review user roles and access configurations

Show the technical text from the sources
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.
