Vulnerability Title
Product Filter for WooCommerce by WBW <= 3.4.6 - Missing Authorization to Unauthenticated Information Disclosure via filterSettings[default_query] Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Product Filter for WooCommerce by WBW plugin for WordPress is vulnerable to Missing Authorization / Information Disclosure in all versions up to, and including, 3.4.6 via the 'filterSettings[default_query]' parameter of the 'filtersFrontend' AJAX action. The handler is registered as 'wp_ajax_nopriv_filtersFrontend' and performs no capability or nonce check; raw POST data is JSON-decoded into $filterSettings and the attacker-controlled 'default_query' array is unconditionally array_merge()'d into the WP_Query arguments, overriding the plugin's safe defaults (most notably post_status, post_type, posts_per_page, and nopaging). This makes it possible for unauthenticated attackers to enumerate non-public WooCommerce products (draft, future, pending) — including their count and rendered listing markup — and to force unbounded queries that load all products in a single request.
