Wazuh Manager permits superuser login with empty password

CVE-2026-74035 · published 2 days ago
Summary

Versions of Wazuh Manager from 4.6.0 up to 4.14.7 let a delegated administrator set a user’s password to blank, which bypasses the normal checks and allows access to the superuser account without a password. This could let an attacker take full control of the monitoring system. Upgrade to version 4.14.8 or later, or apply the vendor’s recommended patch, to close the gap.

What to do
  • Update wazuh wazuh-manager to version 4.14.8 or later.

Original advisory text
Wazuh 4.6.0 before 4.14.8 Authentication Bypass via Empty Password in update_user
Wazuh versions from 4.6.0 before 4.14.8 contain an authentication bypass vulnerability where security.update_user places the reserved user guard and password policy inside a falsy truthiness check. A delegated user administrator can send an empty password to the user update endpoint, bypassing the reserved user guard to take over the wazuh superuser account and authenticate with empty credentials.
