**Cross-Site Request Forgery in Kibana Leading to Privilege Escalation**

Cross-Site Request Forgery (CWE-352) in Kibana can lead to privilege escalation via Cross Site Request Forgery (CAPEC-62). A user who is permitted to create visualizations can save a specially crafted Vega visualization that, when it is opened by another user, causes authenticated requests to be issued to Kibana in the context of the viewing user's session.

**Affected Versions:**

> - All versions from 8.19.0 up to and including 8.19.19
> - All versions from 9.0.0 up to and including 9.4.4

**Affected Configurations:**  
All configurations are affected.

**Solutions and Mitigations:**

The issue is resolved in versions 8.19.20 and 9.4.5.

**For Users that Cannot Upgrade:**

**Self-Managed**  
Disable the Vega visualization type by setting vis\_type\_vega.enabled: false in kibana.yml and restarting Kibana. Existing Vega visualizations and any dashboards that embed them will no longer render.

**Cloud**  
Elastic Cloud Hosted deployments can apply the same setting through the Kibana user settings override in the Cloud Console, where that setting is permitted for the deployment version.

**Indicators of Compromise (IOC)**

No specific indicators of compromise have been identified for this vulnerability.

**Elastic Cloud Serverless**

Due to our continuous deployment and patching model, the vulnerability described in this security advisory was remediated in our Elastic Cloud Serverless offering before the public disclosure.

**Severity:** CVSSv3.1: High ( 7.3 ) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N  
**CVE ID:** CVE-2026-72658
