      "value": "The WP Discourse plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.5.9. This is due to the plugin unconditionally sending Discourse API credentials (Api-Key and Api-Username headers) to any host specified in a post's discourse_permalink custom field during comment synchronization. This makes it possible for authenticated attackers, with author-level access and above, to exfiltrate sensitive Discourse API credentials to attacker-controlled servers, as well as query internal services and potentially perform further attacks."

      "lang": "es",
      "value": "El plugin WP Discourse para WordPress es vulnerable a la Exposición de Información en todas las versiones hasta la 2.5.9, inclusive. Esto se debe a que el plugin envía incondicionalmente credenciales de la API de Discourse (encabezados Api-Key y Api-Username) a cualquier host especificado en el campo personalizado discourse_permalink de una publicación durante la sincronización de comentarios. Esto hace posible que atacantes autenticados, con acceso de nivel de autor y superior, exfiltren credenciales sensibles de la API de Discourse a servidores controlados por el atacante, así como consultar servicios internos y potencialmente realizar ataques adicionales."
