Descriptions

The EventPrime WordPress plugin before 3.2.0 does not sanitise and escape a parameter before outputting it back in the page, leading to an HTML Injection on the plugin in the search area of the website.

El complemento EventPrime de WordPress anterior a 3.2.0 no sanitiza ni escapa un parámetro antes de devolverlo a la página, lo que genera una inyección de HTML en el complemento en el área de búsqueda del sitio web.

The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Reflected HTML Content Injection via the search parameter in all versions up to 3.2.0 (exclusive) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web content in search pages if they can successfully trick a user into performing an action such as clicking on a link.
