The WordPress Portfolio Builder – Portfolio Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'add_video' function in all versions up to, and including, 1.1.7. This makes it possible for unauthenticated attackers to add arbitrary videos to any portfolio gallery.
