- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

## Affected

- Unknown miniOrange 2FA: from 6.2.9, fixed in 6.3.1

## Description

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.

## What to do

- Check your stack: if you ship or depend on Unknown miniOrange 2FA, upgrade to a fixed version (6.3.1) per the references below.
