Metagauss · Registrationmagic

The RegistrationMagic plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.2.1.0.

This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.
