Vulnerability in wazuh-manager

[ Description ]Official description

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.
