The Admin Safety Guard — Login Security, Limit Logins, 2FA & Brute Force Protection WordPress plugin before 1.4.0 does not perform any capability check on one of its REST API endpoints, allowing unauthenticated attackers to retrieve the full list of registered users including their usernames, email addresses, roles, and two-factor authentication enrollment status.
