CVE-2026-63143: CWE-862 Missing Authorization in Elastic Kibana
CVE-2026-63143 is a missing authorization vulnerability in Elastic Kibana versions 9.3.0 and 9.4.0. It allows users with limited feature privileges to access workflow execution outputs in their Kibana space without proper authorization. This unauthorized access can lead to disclosure of sensitive information returned by workflow steps, including data from connected sources that the user should not be able to access. The vulnerability has a medium severity with a CVSS score of 4.3.
AI Analysis
Technical Summary
This vulnerability (CWE-862) in Elastic Kibana affects versions 9.3.0 and 9.4.0, where insufficient authorization checks allow users with limited privileges to access workflow execution outputs via the documented API. The unauthorized access can expose sensitive information from workflow steps and connected data sources. The CVSS 3.1 base score is 4.3, reflecting a network attack vector with low complexity and requiring low privileges, resulting in limited confidentiality impact without integrity or availability impact. No official patch or remediation level has been published by Elastic as of the data provided.
Potential Impact
An attacker with limited feature privileges can gain unauthorized access to sensitive information within workflow execution outputs in their Kibana space. This could lead to information disclosure of data that the attacker is not authorized to view, potentially exposing confidential or sensitive business data. There is no indication of impact on data integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor Elastic's advisories for updates. Until a fix is available, restrict user privileges carefully to minimize exposure and avoid granting unnecessary feature privileges that could be exploited.
