Descriptions

The Blocksy theme for WordPress is vulnerable to Reflected Cross-Site Scripting via the custom_url parameter in all versions up to, and including, 2.0.50 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

El tema Blocksy para WordPress es vulnerable a Cross-Site Scripting Reflejado a través del parámetro custom_url en todas las versiones hasta la 2.0.50 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios en páginas que se ejecutan si logran engañar a un usuario para que realice una acción como hacer clic en un enlace.
