The Basil recipe theme for WordPress is vulnerable to Persistent Cross-Site Scripting (XSS) via the `post_title` parameter in versions up to, and including, 2.0.4 due to insufficient input sanitization and output escaping. This vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses a compromised page. Because the of the default WordPress validation, it is not possible to insert the payload directly but if the Cooked plugin is installed, it is possible to create a recipe post type (cp_recipe) and inject the payload in the title field. Version 2.0.5 contains a patch for the issue.
El tema Basil recipe para WordPress es vulnerable a Cross-Site Scripting (XSS) a través del parámetro `post_title` en versiones hasta la 2.0.4 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esta vulnerabilidad permite a atacantes autenticados con acceso de nivel de colaborador y superior inyectar scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página comprometida. Debido a la validación predeterminada de WordPress, no es posible insertar la carga útil directamente, pero si el complemento Cooked está instalado, es posible crear un tipo de publicación de receta (cp_recipe) e inyectar el payload en el campo del título. La versión 2.0.5 contiene un parche para el problema.
