The manipulation with an unknown input leads to a improper authorization vulnerability. CWE is classifying the issue as CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on confidentiality. The summary by CVE is:

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user who does not hold the "admin" or "power" Splunk roles could access search query text and job metadata for jobs that belong to other users, including job identifiers, dispatch parameters, result counts, and execution metadata, through an Application Programming Interface (API) implemented as a Representational State Transfer (REST) API. The vulnerability is possible because the REST API does not fully enforce per-user authorization before it includes job information in search job listings.
