Vulnerabilidad · Publicado 16/08/2026
El plugin Platnosci Online Blue Media (Autopay) para WordPress, versiones hasta 5.0.0, es vulnerable a Cross-Site Scripting (XSS) almacenado a través del parámetro POST 'bm_woocommerce_css_editor_content'. La falla reside en el método Css_Editor::handle_save() que carece de validación de capacidades, verificación de nonce y sanitización de entrada, permitiendo a atacantes inyectar código malicioso sin autenticación. Este vector impacta tiendas de comercio electrónico en LATAM que dependen de WooCommerce para procesar pagos y gestionar inventario.
The Platnosci Online Blue Media (Autopay) plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.0.0 via the 'bm_woocommerce_css_editor_content' POST parameter. This is due to the Css_Editor::handle_save() method being wired to the WordPress 'init' hook by Settings_Manager::init_once() with no capability check, no nonce verification, and no sanitization on the input — the raw $_POST value is written to the 'woocommerce_bluemedia_settings' option via update_option(), then later echoed directly inside a <style> block on the WooCommerce checkout page by Css_Frontend::print_to_wp_head() with no output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page (the checkout page).
