Description
The Broadstreet plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the create_advertiser AJAX action in all versions up to, and including, 1.53.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create advertisers.
