The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.15.5 via the wppb_save_avatar_value() function due to missing validation on a user controlled key.
