Until a patch is available, consider restricting access to Kibana APIs to trusted users and monitoring for unusual payload sizes or resource usage patterns if feasible.
Description
CVE-2026-33464 is a medium severity vulnerability in Elastic Kibana affecting versions 8.0.0, 9.0.0, and 9.4.0. It involves uncontrolled resource consumption (CWE-400) where an authenticated user with low privileges can send an oversized payload to an internal API. This causes the Kibana process to exhaust system resources, leading to denial of service by making the service unresponsive until recovery or restart. There is no confirmed patch or official remediation available at this time.
