Vulnerability Title
Authorization Bypass Through User-Controlled Key in Kibana Leading to Unauthorized Query Execution on Managed Hosts
Source: CVE Program / CVE List V5
Vulnerability Description
Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized query execution against Elastic Agents that are assigned to a Kibana space the requesting user has no access to, via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). A user who is authorized to run Osquery live queries in one space can have a query carried out on hosts belonging to another space, resulting in disclosure of information from those hosts to the Osquery results data stream.
