Description

The RegistrationMagic plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.0.7.4. This is due to missing nonce verification and capability checks on the rm_set_otp AJAX action handler. This makes it possible for unauthenticated attackers to modify arbitrary plugin settings, including reCAPTCHA keys, security settings, and frontend menu titles.
