This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the random_button_html() function directly concatenates the 'cat' and 'nocat' parameters into HTML data-attributes without esc_attr(), and the 'text' parameter into HTML content without esc_html(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}, {"lang": "es", "value": "El plugin WP Random Button para WordPress es vulnerable a Cross-Site Scripting Almacenado a trav\u00e9s de los atributos del shortcode 'cat', 'nocat' y 'text' del shortcode 'wp_random_button' en todas las versiones hasta la 1.0, inclusive.
