CVE-2026-78601 PUBLISHED

Missing Authorization in Kibana Leading to Unauthorized Elasticsearch Index Data Exposure

Assigner: elastic
Reserved: 24.08.2026 Published: 02.09.2026 Updated: 02.09.2026

Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Privilege Abuse (CAPEC-122). An authorization control was not applied to a Kibana Entity Store configuration operation, allowing an authenticated user with elevated Kibana privileges to indirectly cause a background task to read from Elasticsearch indices that user is not authorized to access. Derived entity data from those indices is then exposed through the entity store output.
