The Booster for WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the validateproductinputfieldsonaddtocart function in versions 4.0.1 to 7.2.4.

This requires the Email Verification module to be active in the plugin and the Login User After Successful Verification setting to be enabled, which it is by default.
