CVE-2023-46231Network attack vector

Session token disclosure via internal log writes

Published Jan 30, 2024 · Updated Feb 28, 2025

Information disclosure in Splunk Add-on Builder before 4.1.4 allows attackers to obtain session tokens from internal logs. The application records active tokens when Add-on Builder is visited or used to build or edit a custom app or add-on. Access requires local log-file access or administrative access to internal indexes, and exposed tokens carry the associated session permissions.
