Description
The XPlainer – WooCommerce Product FAQ [WooCommerce Accordion FAQ Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions (i.e. ffw_insert_new_faq, ffw_hide_discount_notice, ffw_delete_all_faqs, ffw_delete_single_faq, etc...) in all versions up to, and including, 1.7.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to add new and update existing FAQs, FAQ lists, and modify FAQ associations with products.
