CVE-2026-18442: WCFM Marketplace <= 3.8.2 - Unauthenticated SQL Injection via 'wcfmmp_user_location_lat' / 'wcfmmp_user_location_lng' Parameter
The WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress is vulnerable to generic SQL Injection via the 'wcfmmpuserlocationlng' parameter in all versions up to, and including, 3.8.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
