An application programming interface endpoint accepts a user-supplied value and interpolates it directly into the path of a backend request to the underlying search and analytics data store, without restricting its contents. This allows an authenticated attacker to substitute an arbitrary backend path, causing the application's own elevated service credentials to be used against unintended internal endpoints. This could allow an attacker to enumerate or read internal configuration and administrative data from the backend data store that would otherwise be restricted.
