title: Splunk Authentication Token Exposure in Debug Log in Splunk Enterprise
description: In Splunk Enterprise versions below 9.2.1, 9.1.4, and 9.0.9, the software potentially exposes authentication tokens during the token validation process. This exposure happens when either Splunk Enterprise runs in debug mode or the JsonWebToken component has been configured to log its activity at the DEBUG logging level.
problem types: Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.
