Description
The WPBifröst – Instant Passwordless Temporary Login Links plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the ctl_create_link AJAX action in all versions up to, and including, 1.0.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create new administrative user accounts and subsequently log in as those.
