      "value": "The fyyd podcast shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fyyd-podcast', 'fyyd-episode', and 'fyyd' shortcodes in all versions up to, and including, 0.3.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'color', 'podcast_id', and 'podcast_slug'. These attributes are directly concatenated into inline JavaScript within single-quoted string arguments without any escaping or sanitization, allowing an attacker to break out of the JavaScript string context. 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 y un escape de salida insuficientes en atributos de shortcode proporcionados por el usuario, como 'color', 'podcast_id' y 'podcast_slug'. Estos atributos se concatenan directamente en JavaScript en línea dentro de argumentos de cadena entre comillas simples sin ningún escape o sanitización, lo que permite a un atacante salir del contexto de cadena de JavaScript. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
