WordPress WooCommerce Plugin Authentication Bypass

The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Authentication Bypass.

Versions up to, and including, 4.8.6 are affected. This is due to the handle_email_otp_return() function returning the secret magic login token in the response to a publicly accessible OTP request, rather than only delivering it to the user's email address.

This allows unauthenticated attackers to log in as any user on the site, including administrators, if they know that user's email address.
