Advisory

Source description from Wordfence Intelligence, credited to Yuki Haruma.

The Display custom fields in the frontend – Post and User Profile Fields plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the display_object_data_shortcode function referenced by the vg_display_data shortcode in versions up to, and including, 1.2.0. This makes it possible for authenticated attackers , with subscriber-level access and above, to access other users' metadata.
