Ultimate Member < 2.0.40 - Cross-Site Request Forgery (CSRF)
According to the original researcher:
"A CSRF vulnerability in a logged-in user's profile edit form in the Ultimate Member plugin 2.0.38 for WordPress allows attackers to become admin and subsequently extract sensitive information and execute arbitrary code. This occurs because
the attacker can change the e-mail address in the administrator profile, and then the attacker is able to reset the administrator password using the WordPress 'password forget' form."
