The summary by CVE is:

The LoginPress Pro plugin for WordPress is vulnerable to Authentication Bypass via Unverified OAuth Email in all versions up to and including 6.2.3. The vulnerability exists in the loginpress_on_discord_login() Discord OAuth callback handler, which accepts the email field returned by Discord's /users/@me endpoint without ever checking that the profile's verified flag is true, then directly maps that email to a local WordPress account via get_user_by('email', $profile['email']) and issues an authenticated session cookie via wp_set_auth_cookie(). This makes it possible for unauthenticated attackers to take over any existing WordPress account — including administrator accounts — by registering a Discord account configured with an unverified email address that matches the target user's registered WordPress email and completing the standard Discord OAuth flow.
