The wpDataTables ?? Tables & Table Charts premium WordPress plugin before 3.4.2 has Improper Access Control. A low privilege authenticated user that visits the page where the table is published can tamper the parameters to access the data of another user that are present in the same table by taking over the user permissions on the table through formdata[wdt_ID] parameter. By exploiting this issue an attacker is able to access and manage the data of all users in the same table.
