The advisory
The Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin before 2.191 does not verify the account password before accepting an authenticator-app two-factor code at login, allowing anyone who holds a user's current authenticator code to log in as that user, including an administrator, without the password.
