# WordPress 2FA plugin lets password-holding attacker bypass second factor via passkey

The miniOrange 2FA WordPress plugin before 6.3.1 lets a pending passkey login register an extra passkey on an account that already has one. An attacker who knows a user's password can add their own authenticator and get past the second factor.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed miniOrange 2FA plugin version in the WordPress admin plugins list or with `wp plugin get miniorange-2-factor-authentication --field=version` (plugin slug unknown from sources; verify the slug)
- Confirm whether passkey login is enabled in the plugin settings

## Fix

- Update the miniOrange 2FA plugin to `6.3.1` or later
- Review each user's registered passkeys and remove any that are unrecognized

## From the sources

The miniOrange 2FA  WordPress plugin before 6.3.1 does not prevent a pending passkey login from registering an additional passkey on an account that already has one configured, allowing an attacker who knows a user's password to add their own authenticator and bypass the second factor.
