CVE-2026-33434 Details
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.
A logic error has been identified in Wazuh versions 4.6.0 and above, prior to 4.14.5. The issue resides in the CheckRateLimitsMiddleware.dispatch() function, where the /events endpoint's rate check improperly overrides the general rate limit. As a result, when the global max_request_per_minute limit is surpassed, requests to /events can still be processed if the events-specific limit of 30 requests per minute has not been reached. This flaw enables event injection into analysisd, bypassing the globally configured rate limits.
Users can upgrade to Wazuh version 4.14.5 or later to address this vulnerability.
