CVE-2026-33434: Wazuh

High severity, CVSS 7.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Wazuh Wazuh: from 4.6.0, before 4.14.5 (fixed in 4.14.5)
