Incorrect Authorization in Kibana Leading to Unauthorized Cross-Space Exposure of Machine Learning Job Data

Publisher and source text is retained separately from QFinch interpretation.

QFinch assessment

Incorrect Authorization (CWE-863) in the Kibana machine learning feature can lead to information disclosure via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user holding machine learning job management privileges within a single Kibana space could cause a job's saved object to become accessible across all spaces in the Kibana instance, without holding access rights to those additional spaces.
