CVE-2023-0490

Estado: ModificadaMedia (5.4)—

El plugin f(x) TOC para WordPress hasta la versión 1.1.0 no valida ni escapa algunos de sus atributos de shortcode antes de mostrarlos de nuevo en una página o entrada donde se incrusta el shortcode, lo que podría permitir a usuarios con el rol de colaborador y superiores llevar a cabo ataques de secuencias de comandos en sitios cruzados (XSS) almacenadas.
