The RegistrationMagic WordPress plugin before 6.0.2.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Metagauss User Registration Forms RegistrationMagic allows Reflected XSS. This issue affects RegistrationMagic: from n/a through 6.0.3.3.
The RegistrationMagic – User Registration Plugin with Custom Registration Forms plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 6.0.2.6. This is due to the plugin not properly validating the password reset token prior to updating a user's password. This makes it possible for unauthenticated attackers to reset the password of arbitrary users, including administrators, and gain access to these accounts.
