## Description

The SecuPress with Simple SSL plugin for WordPress is vulnerable to a restriction bypass via the REST API users endpoint and the profile email-change confirmation link in all versions up to, and including, 2.7.3. This is due to the Forbid Same Email Domain feature checking the address only in the user_profile_update_errors and registration_errors hooks, which neither of those paths runs. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change their account email to an address on the site's own domain when the feature is enabled.
