      "value": "The WP Random Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cat', 'nocat', and 'text' shortcode attributes of the 'wp_random_button' shortcode in all versions up to, and including, 1.0. 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."

Esto se debe a una sanitización de entrada insuficiente y un escape de salida inadecuado en los atributos del shortcode proporcionados por el usuario. Específicamente, la función random_button_html() concatena directamente los parámetros 'cat' y 'nocat' en atributos de datos HTML sin esc_attr(), y el parámetro 'text' en contenido HTML sin esc_html(). Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
