CVE-2026-102410: CWE-862 Missing Authorization in Elastic Kibana
Description
Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal API surface within the Metrics Experience feature did not enforce a Kibana-level authorization check that an equivalent, related API in the same feature did enforce. As a result, a user who held only data-store-level read access to an index, but no corresponding Kibana feature privilege, could retrieve index-derived metric data through Kibana that the properly-authorized API would otherwise have blocked.

Technical Analysis
This vulnerability (CWE-862) in Kibana arises from an internal API in the Metrics Experience feature that lacks proper authorization enforcement at the Kibana feature privilege level. While a related API enforces these checks, this API allows users who have only data-store-level read access but lack the necessary Kibana feature privileges to access index-derived metric data. This results in unauthorized information disclosure through Kibana.
Potential Impact
The vulnerability allows unauthorized users with limited data-store read permissions to access metric data via Kibana that should be restricted by Kibana feature privileges. This leads to information disclosure but does not affect data integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the current data. Users should monitor Elastic's advisories for updates and apply any forthcoming patches promptly.
