CVE-2020-19850Public exploitNetwork attack vector

Service interruption via unrestricted repeated requests

Published Apr 4, 2023 · Updated Feb 14, 2025

Uncontrolled resource consumption in Directus API 2.2.0 allows remote authenticated users to interrupt service with repeated HTTP requests. The API reprocesses large bursts of identical requests without an anti-automation control, allowing request work to exhaust server resources. A legitimate authenticated account is required, and the demonstrated consequence is application unavailability rather than data access or modification.
