Advisory
Source description from Wordfence Intelligence, credited to stealthcopter.
The SurveyJS: Drag & Drop WordPress Form Builder to create, style and embed multiple forms of any complexity plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 1.9.136. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
