      "value": "The WordPress File Sharing Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 2.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled."

Esto hace posible que atacantes autenticados, con permisos de nivel de administrador y superiores, inyecten scripts web arbitrarios en p\u00e1ginas que se ejecutar\u00e1n cada vez que un usuario acceda a una p\u00e1gina inyectada. Esto solo afecta a las instalaciones multisitio y las instalaciones en las que se ha deshabilitado \"unfiltered_html\"."
