The WP Go Maps (formerly WP Google Maps) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘wpgmza_custom_js’ parameter in all versions up to, and including, 10.0.05 due to insufficient input sanitization and output escaping and missing capability check in the 'admin_post_wpgmza_save_settings' hook anonymous function.
