Summary

Elastic Kibana from 8.7.0 through 8.19.23, from 9.0.0 through 9.4.8, and from 9.5.0 through 9.5.5 is affected. A user-controlled key lets authorization checks be bypassed (CWE-639). An authenticated user with read access to connectors in one Kibana space can retrieve connector execution logs from other spaces, including connector names, execution status, timestamps and error messages.

Description from the CNA

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with read access to connectors in one Kibana space can retrieve connector execution log information from other spaces that they are not authorized to access. The disclosed information includes connector names and identifiers, execution status, timestamps, error messages, and aggregated execution statistics.
