Descriptions

The MF Gig Calendar WordPress plugin before 1.2 does not sanitise and escape the id GET parameter before outputting back in the admin dashboard when editing an Event, leading to a reflected Cross-Site Scripting issue

El plugin MF Gig Calendar de WordPress versiones hasta 1.1, no sanea o escapa del parámetro id GET antes de mostrarlo en el panel de administración cuando se edita un evento, conllevando a un problema de tipo Cross-Site Scripting reflejado

The MF Gig Calendar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'id' GET parameter in versions up to, and including, 1.1 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.
