Title
Bot for Telegram on WooCommerce <= 1.3.0 - Unauthenticated Authentication Bypass to Account Takeover via Fake Telegram Webhook + Brute-Forced Login Token
Summary
The Bot for Telegram on WooCommerce plugin for WordPress is vulnerable to Authentication Bypass leading to Account Takeover in all versions up to, and including, 1.3.0. The `/wp-json/woo-telegram/v1/main/` REST endpoint is registered with `permission_callback => '__return_true'` and performs no Telegram webhook signature verification, allowing an unauthenticated attacker to POST a forged bot update with a `message.chat.id` set to any WordPress login name; `bftow_get_user_system_id()` resolves this attacker-supplied value to the targeted account via `get_user_by('login', $tgId)` with no ownership proof, and writes a login token computed as `md5($_SERVER['HTTP_USER_AGENT'] . time())` — both inputs are fully attacker-controlled or bounded within seconds using the response's own `Date` header. The resulting token is redeemable at the unauthenticated, capability-check-free, and nonce-less `?action=bftow_create_order&bftow_token=` endpoint, which calls `wp_set_auth_cookie()` unconditionally via `login_user_by_id`, issuing a persistent authenticated session cookie for the targeted account to the attacker. This makes it possible for unauthenticated attackers to log in as any WordPress user, including administrators, given only that user's username.

              "value": "The Bot for Telegram on WooCommerce plugin for WordPress is vulnerable to Authentication Bypass leading to Account Takeover in all versions up to, and including, 1.3.0. The `/wp-json/woo-telegram/v1/main/` REST endpoint is registered with `permission_callback =\u003e \u0027__return_true\u0027` and performs no Telegram webhook signature verification, allowing an unauthenticated attacker to POST a forged bot update with a `message.chat.id` set to any WordPress login name; `bftow_get_user_system_id()` resolves this attacker-supplied value to the targeted account via `get_user_by(\u0027login\u0027, $tgId)` with no ownership proof, and writes a login token computed as `md5($_SERVER[\u0027HTTP_USER_AGENT\u0027] . time())` \u2014 both inputs are fully attacker-controlled or bounded within seconds using the response\u0027s own `Date` header. The resulting token is redeemable at the unauthenticated, capability-check-free, and nonce-less `?action=bftow_create_order\u0026bftow_token=` endpoint, which calls `wp_set_auth_cookie()` unconditionally via `login_user_by_id`, issuing a persistent authenticated session cookie for the targeted account to the attacker. This makes it possible for unauthenticated attackers to log in as any WordPress user, including administrators, given only that user\u0027s username."
