Descriptions

The EventPrime WordPress plugin before 3.2.0 does not sanitise and escape some parameters before outputting them back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin.

El complemento EventPrime de WordPress anterior a 3.2.0 no sanitiza ni escapa algunos parámetros antes de devolverlos a la página, lo que genera un Cross-Site Scripting reflejado que podría usarse contra usuarios con privilegios elevados, como el administrador.

The EventPrime plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the keyword and ep_filter_date parameters in versions up to 3.2.0 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.
