What it is

The Welcart e-Commerce WordPress plugin before 2.8.6 does not validate user input before using it in file_exist() functions via various AJAX actions available to any authenticated users, which could allow users with a role as low as subscriber to perform PHAR deserialisation when they can upload a file and a suitable gadget chain is present on the blog
