Publication date: 2026-09-02

Last updated on: 2026-09-02

Assigner: Elastic

Description
Incorrect Authorization (CWE-863) in the Kibana machine learning feature can lead to unauthorized resource consumption via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user could invoke machine learning functionality beyond their authorization scope, consuming cluster resources they should not be able to reach.

Executive Summary

CVE-2026-82293 is an Incorrect Authorization vulnerability in Kibana's machine learning feature. It allows authenticated users to bypass access controls and consume cluster resources they are not authorized to use. The issue arises from misconfigured security levels in the access control system.

Detection Guidance

To detect this vulnerability, check if your Kibana instance is running a vulnerable version (8.19.20 or earlier, 9.4.5 or earlier, 9.5.1 or earlier). Use commands like 'curl -X GET http://<kibana-host>:<port>/api/status' to check the version. If the version is below the patched releases (8.19.21, 9.4.6, 9.5.2), the system is vulnerable.

Impact Analysis

This vulnerability could allow unauthorized users to consume cluster resources, potentially leading to degraded performance or denial of service for legitimate users. It requires an authenticated user to exploit, but does not grant additional privileges beyond resource consumption.

Mitigation Strategies

Immediately upgrade Kibana to a non-vulnerable version: 8.19.21, 9.4.6, or 9.5.2. If upgrading is not possible, consider disabling the machine learning feature or restricting access to authenticated users with minimal required permissions.
