Wazuh: Rate Limit Bypass via /events Endpoint

Published Jul 16, 2026 · Updated Jul 18, 2026 · Assigned by GitHub_M

Description

Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 4.6.0 and above, prior to 4.14.5, a logic error in CheckRateLimitsMiddleware.dispatch() causes the /events endpoint rate check to unconditionally overwrite the general rate limit result. When the global max_request_per_minute is exceeded, requests to /events still succeed if the events-specific counter (hardcoded 30/min) has not been reached. This allows event injection into analysisd beyond the admin-configured global rate limit. This issue has been fixed in version 4.14.5.
