  • Disclosed: 07.09.2021
  • Updated: 11.10.2026 10:22

Sixteen XforWooCommerce Add-On Plugins for WordPress are vulnerable to authorization bypass due to a missing capability check on the wp_ajax_svx_ajax_factory function in various versions listed below.

The plugins impacted are: Product Filter for WooCommerce < 8.2.0, Improved Product Options for WooCommerce < 5.3.0, Improved Sale Badges for WooCommerce < 4.4.0, Share, Print and PDF Products for WooCommerce < 2.8.0, Product Loops for WooCommerce < 1.7.0, XforWooCommerce < 1.7.0, Package Quantity Discount < 1.2.0, Price Commander for WooCommerce < 1.3.0, Comment and Review Spam Control for WooCommerce < 1.5.0, Add Product Tabs for WooCommerce < 1.5.0, Autopilot SEO for WooCommerce < 1.6.0, Floating Cart < 1.3.0, Live Search for WooCommerce < 2.1.0, Bulk Add to Cart for WooCommerce < 1.3.0, Live Product Editor for WooCommerce < 4.7.0, and Warranties and Returns for WooCommerce < 5.3.0.
