Description

The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Authentication Bypass in versions up to, and including, 4.8.6. 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 makes it possible for unauthenticated attackers to log in as any user on the site, including administrators, if they know that user's email address.
