Privilege Escalation in Kibana Agent Builder

Publication date: 2026-08-13

Last updated on: 2026-08-13

Assigner: Elastic

Description
Kibana Agent Builder does not correctly verify that the requesting user holds the privileges required by a separate Kibana feature before it creates and runs a tool that invokes that feature's functionality. This allows privilege escalation and could lead to disclosure of sensitive information that the user is not authorized to read.

Executive Summary

Kibana Agent Builder fails to check if a user has required privileges before running a tool that uses another Kibana feature. This allows privilege escalation and potential unauthorized access to sensitive information.

Detection Guidance

Detecting this vulnerability requires checking if your Kibana instance is running a vulnerable version (9.4.0 through 9.4.3). Run the command: curl -X GET "http://localhost:5601/api/status" | grep version to check the version. If the version is below 9.4.4, the system is vulnerable.

Impact Analysis

An attacker with limited access could escalate privileges to view or manipulate data they are not authorized to access, leading to data breaches or unauthorized actions within the system.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements for data protection such as GDPR or HIPAA, which mandate strict access controls and data confidentiality.

Mitigation Strategies

Upgrade Kibana to version 9.4.4 or later immediately. Elastic Cloud Serverless users are already patched. No workarounds exist for users unable to upgrade.
