{"id":"CVE-2026-33434","summary":"Wazuh: Rate Limit Bypass via /events Endpoint","details":"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.","aliases":["GHSA-37qc-8242-6crg"],"modified":"2026-07-21T03:46:34.468228552Z","published":"2026-07-16T23:36:33.929Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-799"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33434.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33434.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-37qc-8242-6crg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33434"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"a6e26aea57cf341a530a948503057de743d8d46e"},{"fixed":"460511d384aadc1d539caa6c4aa6a4234d68c9ba"}],"database_specific":{"cpe":"cpe:2.3:a:wazuh:wazuh:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.6.0"},{"fixed":"4.14.5"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33434.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
