Descriptions

The Post Timeline WordPress plugin before 2.2.6 does not sanitise and escape an invalid nonce before outputting it back in an AJAX response, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

El plugin de WordPress Post Timeline anterior a la versión 2.2.6 no sanea y escapa de un nonce inválido antes de devolverlo en una respuesta AJAX, lo que lleva a un Reflected Cross-Site Scripting que podría ser utilizado contra usuarios con privilegios elevados como el administrador.

The Post Timeline for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 2.2.5 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.
