In Splunk AI Toolkit versions below 5.7.3, a low-privileged user that does not hold the 'admin' or 'power' roles could access confidential data that was restricted through configurations on custom roles. The app contains an configuration file with a entry that modifies the built-in ‘user’ role. Because the Splunk platform combines inherited search filters with the SPL operator, the injected filter overrides more restrictive filters on child roles.
