Technical details

The vulnerability is an improper access control flaw (CWE-862) in the Splunk Enterprise REST API for field extraction and transformation move operations. The API fails to validate whether the destination application is accessible to the requesting user before processing the move, allowing users without "admin" or "power" roles to relocate knowledge objects to restricted apps. This is a local or network-adjacent attack requiring authentication but no additional user interaction.
