CVE-2026-93346Network attack vectorHinoki check available

Login-throttle bypass via check-then-count race

Published Oct 13, 2026 · Updated Oct 13, 2026

A login-throttling race in Wazuh manager before 4.14.8 allows remote attackers to exceed password-guessing limits via concurrent API requests. The check_blocked_ip function checks the source IP before asynchronous credential validation, while prevent_bruteforce_attack counts failures afterward, leaving concurrent attempts unreserved. Exploitation requires network access to the authenticate or run_as login endpoint; account access still requires a correct password.
