CVE-2026-78601
mediumMissing Authorization (CWE-862) in Kibana can lead to information disclosure via Privilege Abuse (CAPEC-122).
Vendor / product: Elastic — kibana
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.
