## Affected

- Unknown Login with QR: through 1.0.0

## Description

The Login with QR WordPress plugin through 1.0.0 does not verify that the code used to log a user in is one it issued, matching any stored user metadata value instead, which allows unauthenticated attackers to log in as any user, including administrators.

## What to do
