A missing authorization vulnerability in Kibana allows authenticated low-privileged users to access endpoint response action records and response content without proper permissions. This occurs because an internal data retrieval function used by Elastic Defend endpoint response actions does not enforce required Security Solution and endpoint privileges, instead retrieving data with elevated internal permissions. The issue affects multiple Kibana versions from 8.12.0 up to but not including 8.19.19, 9.0.0 up to 9.3.8, and 9.4.0 up to 9.4.4. A patch is available to address this vulnerability. No known exploits are reported in the wild.

Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal Kibana data retrieval capability used by Elastic Defend endpoint response actions did not enforce the Security Solution and endpoint privileges that its user-facing equivalents require, and it retrieved data with elevated internal permissions rather than the permissions of the requesting user. As a result, an authenticated low-privileged Kibana user with no Security Solution privileges, endpoint privileges and no Elasticsearch privileges on the underlying data, could read endpoint response action records and the corresponding response content returned by managed hosts.
