Improper Privilege Management vulnerability in smp7, wp.Insider Simple Membership allows Privilege Escalation.This issue affects Simple Membership: from n/a through 4.3.4.

Vulnerabilidad de gestión de privilegios incorrecta en smp7, wp.Insider Simple Membership permite la escalada de privilegios. Este problema afecta a Simple Membership: desde n/a hasta 4.3.4.

The Simple Membership plugin for WordPress is vulnerable to privilege escalation due to missing input validation on the create_swpm_user function in versions up to, and including, 4.3.4. This makes it possible for unauthenticated attackers to register users with arbitrary membership levels. Since membership levels can be granted a higher user role than subscriber, this can lead to privilege escalation
