CVE-2024-29945Network attack vector

Authentication token disclosure via DEBUG validation logging

Published Mar 27, 2024 · Updated Dec 16, 2025

Sensitive data exposure in Splunk Enterprise before 9.0.9, 9.1.4, and 9.2.1 allows attackers to obtain authentication tokens from logs. JsonWebToken validation writes token values into splunkd DEBUG events when global or component-level DEBUG logging is active. Exposure requires enabled token authentication plus local log access or administrative access to internal indexes; these features are disabled or restricted by default.
