**Missing Authorization in Kibana Leading to Unauthorized Elasticsearch Index Data Exposure**

Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Privilege Abuse (CAPEC-122). An authorization control was not applied to a Kibana Entity Store configuration operation, allowing an authenticated user with elevated Kibana privileges to indirectly cause a background task to read from Elasticsearch indices that user is not authorized to access. Derived entity data from those indices is then exposed through the entity store output.

**Affected Versions:**

- 9.x: All versions from 9.4.0 up to and including 9.4.4

Versions prior to 9.4.0, including all 8.x releases, are not affected because the affected functionality did not exist.

**Affected Configurations:**

The vulnerability affects Kibana deployments that meet all of the following conditions: a Platinum or higher subscription (or equivalent trial license) is active; the Entity Store v2 feature has been enabled by an administrator; and the Entity Store has been installed at least once. Deployments where these conditions are not all met are not affected.

**Solutions and Mitigations:**

The issue is resolved in Kibana version 9.4.5.

**For Users that Cannot Upgrade:**  
There are no workarounds for this vulnerability.
