CVE-2026-33434 (GCVE-0-2026-33434)

Vulnerability from cvelistv5 – Published: 2026-07-16 23:36 – Updated: 2026-07-18 03:22

Title

Wazuh: Rate Limit Bypass via /events Endpoint

Summary

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.

Severity

4.3 (Medium)
