**Incorrect Authorization in Kibana Leading to Unauthorized Disabling of Privilege Monitoring**

Incorrect Authorization (CWE-863) in Kibana Entity Analytics can lead to a loss of security monitoring via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only read-level Security feature access, and no Elasticsearch privileges, could stop the recurring Privilege Monitoring engine task for a Kibana space. Privileged user monitoring then stops producing data for that space while the engine continues to report a healthy state to operators.

**Affected Versions:**

> - 9.x:

- All versions from 9.1.0 up to and including 9.4.5
- All versions from 9.5.0 up to and including 9.5.1

Versions prior to 9.1.0, including all 8.x releases, are not affected because the affected functionality did not exist.

**Affected Configurations:**

> - Kibana deployments running an affected version in which the Entity Analytics Privilege Monitoring engine has been initialized. Deployments that never initialized the engine are not exposed.
> - Exploitation requires an authenticated Kibana account with read-level Security feature access in the target space. No Elasticsearch privileges and no administrative privileges are required.
> - Both self-managed and Elastic Cloud Hosted deployments are affected. No non-default configuration is required.

**Solutions and Mitigations:**

The issue is resolved in Kibana versions 9.4.6 and 9.5.2.
