## Description

The Request For Quote plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'product_id' and 'variation_id' parameters of the public wpheka_add_to_quote and wpheka_add_to_quote_shop AJAX actions in all versions up to, and including, 1.8.3. This is due to missing validation that the supplied product exists, is published and is eligible for the quote button, and that a supplied variation is a published variation of that product. This makes it possible for unauthenticated attackers to add draft, private or excluded products to their quote list and view details of unpublished products, such as name, image, SKU and price, on the quote list page.
