## Description

The WCFM – Frontend Manager for WooCommerce plugin for WordPress is vulnerable to Missing Authorization via the inquiry form submission handler in all versions up to, and including, 6.8.1, due to the handler not enforcing the 'Inquiry with login' setting, which was applied only when the form was displayed, and not validating the submitted product and vendor IDs. This makes it possible for unauthenticated attackers to submit inquiries when the site requires login, and to file inquiries against non-public products or users who are not vendors.
