Advisory

Source description from Wordfence Intelligence, credited to Karthik.

The Security by CleanTalk plugin for WordPress is vulnerable to Two-Factor Authentication Bypass in all versions up to, and including, 2.190. This is due to missing verification that the first authentication factor (password) had been successfully completed before accepting a submitted authenticator-app or email two-factor code, allowing the second factor to be submitted in isolation. This makes it possible for unauthenticated attackers to log in as any user who has two-factor authentication enabled, including administrators, by supplying only a valid TOTP code without knowing the account password. Two-factor authentication must be enabled for the targeted user account.
