Improper Object Attribute Modification in Elastic Security Kibana

Publication date: 2026-08-13

Last updated on: 2026-08-13

Assigner: Elastic

Description
Improperly Controlled Modification of Dynamically-Determined Object Attributes (CWE-915) in the case management functionality of Elastic Security in Kibana can lead to unauthorized modification of case data by an authenticated user who has not been granted case editing privileges, via Manipulating User-Controlled Variables (CAPEC-77). Object attributes accepted by the case management API were not subject to the same authorization enforcement applied in the user interface, so a low-privileged user could alter case records they were only entitled to view.

Executive Summary

CVE-2026-72655 is a vulnerability in Elastic Security for Kibana where authenticated users without case editing privileges can modify case data. This happens because the case management API does not enforce the same authorization checks as the user interface, allowing manipulation of user-controlled variables to alter case records they can only view.

Detection Guidance

To detect this vulnerability, check if your Kibana instance is running a vulnerable version (8.0.0 through 8.19.19 or 9.0.0 through 9.4.4). Verify the version using commands like 'curl -X GET "http://localhost:5601/api/status"' or check the Kibana logs for version details.

Impact Analysis

This vulnerability allows unauthorized users to modify case data they should only be able to view. This could lead to incorrect or tampered case records, potentially affecting investigations, compliance reporting, or decision-making processes within your organization.

Compliance Impact

This vulnerability could impact compliance by allowing unauthorized modifications to sensitive case data, potentially violating integrity requirements in regulations like GDPR or HIPAA. Unauthorized changes to records may lead to non-compliance with data integrity and audit trail requirements.

Mitigation Strategies

Upgrade Kibana to a non-vulnerable version (8.19.20 or later, or 9.4.5 or later). If upgrading is not possible, consider migrating to Elastic Cloud Serverless, which is not affected by this issue.
