"value": "The OTP Login & Register Woocommerce plugin for WordPress is vulnerable to Authentication Bypass via OTP Brute Force in all versions up to, and including, 2.7.2. The vulnerability exists because the OTP rate-limit attempt counter in `process_otp_form` is keyed exclusively on the attacker-controlled `xoo_ml_user_ip_data` cookie's `ip_address` field, allowing unlimited counter resets by simply rotating the cookie, while the OTP itself is generated with PHP's non-cryptographic `rand()` function over a default space of only 9,000 possible values (1000–9999), and both the OTP issuance endpoint (`xoo_ml_login_with_otp`) and verification endpoint (`xoo_ml_otp_form_submit`) are registered as unauthenticated `wp_ajax_nopriv` actions with no nonce or capability checks. This makes it possible for unauthenticated attackers to brute-force the OTP for any registered account and obtain a full WordPress authentication session — including for administrator accounts — via `wp_set_auth_cookie()` in `login_user_with_otp()`. Exploitation requires the attacker to know the target user's registered phone number, which is used to trigger OTP issuance via the unauthenticated `xoo_ml_login_with_otp` endpoint."
