The Product Input Fields for WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the addproductinputfieldstoorderitemmeta() function in all versions up to, and including, 1.12.0. This may make it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Please note that by default the plugin is only vulnerable to a double extension file upload attack, unless an administrators leaves the accepted file extensions field blank which can make .php file uploads possible. Please note 1.12.2 was mistakenly marked as patched while 1.12.1 was marked as vulnerable for a short period of time, this is not the case and 1.12.1 is fully patched.

The Product Input Fields for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.9 via the handledownloads() function due to insufficient file path validation/sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
