Descriptions

The EventON WordPress plugin before 4.5.5, EventON WordPress plugin before 2.2.7 do not properly sanitise and escape a parameter before outputting it back in pages, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

El complemento EventON WordPress anterior a 4.5.5 y el complemento EventON WordPress anterior a 2.2.7 no sanitizan ni escapan adecuadamente un parámetro antes de devolverlo a las páginas, lo que genera cross site scripting reflejado que podría usarse contra usuarios con privilegios elevados, como el administrador.

The EventON plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'eid' parameter in all versions up to, and including, 4.5.4 (premium) & 2.2.7 (free) 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.
