Abilities Bridge < 1.4.2 - Administrator Account Creation via CSRF

The Abilities Bridge WordPress plugin before 1.4.2 does not require a valid nonce before re-authenticating a REST API request from the logged-in session cookie, allowing attackers to make a logged-in administrator perform any REST API action, including creating a new administrator account and taking over the site, by tricking them into opening a crafted page (CSRF).
