What the vulnerability does
The Embed PDF for WPForms plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ajax_handler_download_pdf_media function in all versions up to, and including, 1.1.5. 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.

What an attacker can do
Upload malicious files to the site and execute code with site-level permissions.
Potential impact on your site
Compromised site with potential data theft, malware injection, or complete takeover by any authenticated user.
Conditions required to exploit
