Summary
Elastic Kibana versions from 8.0.0 through 8.19.23, from 9.0.0 through 9.4.8, and from 9.5.0 through 9.5.5 contain an authorization bypass through a user-controlled key (CWE-639). An authenticated user with Machine Learning read access in one Kibana space can read audit and error messages of data frame analytics jobs in other spaces that the user is not authorized to access. These messages can expose destination index names, analyzed field names, and failure information.

Description from the CNA
Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana Machine Learning can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with Machine Learning read access in one Kibana space can read the audit and error messages of data frame analytics jobs that belong to other spaces that the user is not authorized to access. These messages can include job details such as destination index names, analyzed field names, and failure information.
